These crawls are part of an effort to archive pages as they are created and archive the pages that they refer to. That way, as the pages that are referenced are changed or taken from the web, a link to the version that was live when the page was written will be preserved.
Then the Internet Archive hopes that references to these archived pages will be put in place of a link that would be otherwise be broken, or a companion link to allow people to see what was originally intended by a page's authors.
The goal is to
fix all broken links on the web .
Crawls of supported "No More 404" sites.
A daily crawl of more than 200,000 home pages of news sites, including the pages linked from those home pages. Site list provided by

2009 was a remarkable year for developers. Vic Gundotra, VP of our developer team declared at Google I/O, "The web has won!" and this year was full of launches and announcements that remind us how the web has become the platform of our day. We found lots of inspiration from the developers at Google I/O in San Francisco and at our Google Developer Days in Japan, China, Brazil, Russia and the Czech Republic.Faster Apps Faster - the theme for the recent Campfire One event letting developers know how GWT 2.0 decreases development time (it's being used by Google Wave & Adwords for this reason) and how Speed Tracer gives you new insight into speeding up your appsMake the Web faster - as part of an effort to Make the web faster we launched tools like Page-Speed and our DNS resolution service . We also made our internal JavaScript tools available, called Closure Tools , so you can rev up your js like the guys on Gmail. With PubSubHubbub all your feeds can be real-time streams.A faster browser - A few weeks ago we launched Google Chrome for Mac and Linux, along with an extension framework for Chrome and a gallery for developers to distribute their extensions -- there are over 900 to check out already ! Chrome has a set of developer tools built on WebKit to help optimize your code. Plus, we released details of Chrome OS ...a netbook operating system for speed freaks. Along the way, we've worked with the larger web community contributing to the exciting future of the web with HTML5 .Mobile - Android launched on one device in one country on one carrier in 2008. This year, 20 devices in 26 countries on 32 carriers have been launched or announced. Developers have created over 16,000 apps in the Android Marketplace . Some were winners of our second Android Developer Challenge . We launched new mobile versions of gmail and calendar using HTML5 . You can take a picture to search using Google Goggles and get turn-by-turn navigation with Google maps . Plus, we recently announced our mobile lab for Android hardware .Hosting - App Engine apps were allowed to scale beyond free quotas and Java developers were invited to try it out at Campfire 1 in April . Developers responded, with over 100K apps built on App Engine. Open source developers using Project Hosting were able to host projects on Mercurial , in addition to Subversion.New APIs - Google Wave was released early to developers at Google I/O in May. Wave is "equal parts conversation and document" and showcases what is possible in the browser. Developers can build robot extensions to automate common tasks or build gadget extensions to provide a new way for users to interact. Google Maps released v3 , Friend Connect got more personalized and then got cozy w/ Twitter , Google Analytics released an API and then added asynchronous tracking .Google Web Elements - From maps to search to translate and more, Google Web Elements made it even easier than ever to add Google products to your site.Labs - Google Code Labs was created to let developers know which APIs and products are cutting edge labs "experiments" and which we are committed to supporting for the long term.By Mike Marchak, on behalf of the Google Developer Team
We know it's easier for developers to program in the languages they know. So we updated the Google Analytics API Python Client library with all the new API version 2 features and added reference exampels for both the Account Feed and Data Feed . Now it's easier than ever to automate your analysis workflow using our API.Taking The Library For a Spin sample application to do just that. The application uses the new Google Analytics Python client library to retrieve metrics for a series of segments. It then performs some calculations on the data and creates bar charts using the GChartWrapper package, an open source Python wrapper for the Google Charts API . Finally, it uses the Python Imaging Library to add a title and legend, and stitches all the charts together into a single image. We decided to release this application as open source so you can create visualizations with your own data.Solving Business Problems Avinash Kaushik , our Analytics Evangelist, to measure "engagement " on his popular Occam's Razor blog . We also wanted to determine if the time he spends participating in social media sites is valuable and sends new readers to his blog.Let's Analyze Far more visits originate from Twitter (3.6x) when compared to Facebook, perhaps not surprising given Avinash's Twitter followers (~16,120) Visitors from Twitter tend to be new visitors, a good thing, but they view fewer pages and spend significantly less time on the blog. On the other hand Facebook delivers an audience that is loyal. These visitors come back to the site more often and spend a significant time on the blog (compared to Twitter and all other visitors). download it here and give it a whirl, we would love to hear your feedback.By Nick Mihailovski, Google Analytics API Team
When I started work at Google, I visited the Google Earth team, hoping to find a 20% project on my favorite Google product. There I met Bruno Bowden, who introduced me to a problem I had never thought much about: how to take browser sizes into account when designing a page.browsersize.googlelabs.com and enter the URL of a page you'd like to examine. The size overlay you see is using latest data from visitors to google.com, so this should give you a pretty good indication of what parts of your UI are generally visible and what aren't.browser-size-external-feedback !By Arthur Blume on behalf of the Google Browser Size team
Over the past few months we've received a lot of great feedback from our developers about what they wanted to see in the Google Analytics API . Today we're excited to announce new powerful and flexible features to the Google Analytics Data Export API including:Support for Advanced Segments advanced segmentation , you can look beyond the totals and into the nuances of the data for your site. For example, the average time on site for all visits could be 60 seconds, but when you segment by country, you might learn that average time on site of visits from Poland is over 2 minutes.Create them on the fly by specifying their expression directly through an API query. Use advanced segments created in the Google Analytics web interface through the API. Goal 5-20 and Configuration Data Custom Variables Custom variables are powerful new ways to describe visitors, visits and pages within Google Analytics. In this new release, we've added 10 new dimensions to access custom variable data. In addition, every custom variable that you've used is now available through the Account Feed.public changelog and public notify group . We've updated all our documentatation at http://code.google.com/apis/analytics . Please continue to give us feedback to improve our product through our public google group .By Nick Mihailovski on behalf of the Google Analytics API Team
Today I'm excited to announce that Google Fusion Tables is releasing its own API. Fusion Tables is a free service for sharing and visualizing data online. It allows you to upload data, share and mark up your data with collaborators, merge data from multiple tables, and create visualizations like charts and maps.Google Maps API and the Google Visualization API so you can view your data in maps, motion charts, and graphs. All of these can be embedded in your webpage, your Google Site, your blog...any Web page you want! The visualizations even update automatically as data is updated or corrected. Embed the visualization once, and the latest version will always be shown automatically.Fusion Tables API , you can update and query your dataset in Fusion Tables programmatically, without ever logging in to the Fusion Tables website. The API means you can import data from whatever data source you may have, whether a text file or a full-powered data base. On the more exotic side, imagine you're collecting data via survey software on GPS-enabled cell phones, as the Open Data Kit project is doing. Open Data Kit uses Google App Engine and the Fusion Tables API to instantly map locations of survey results. By Anno Langen, Jayant Madhavan and Rebecca Shapley, Google Fusion Tables Team
Google Developer Days 2009 , a set of one-day developer events that travel around the world. This year, they started in Beijing, China on June 5 and ended in Moscow, Russia on November 10. At each event, attendees had the opportunity to learn about Google's newest web technologies with products such as Google Wave , Android , Chrome , Google Web Toolkit , OpenSocial , and App Engine . They also interacted with Google developers during "office hours" and had the chance to see how other developers are using Google technologies for their own applications at various demo areas.presentations and photos from our final events of the year, and hopefully each location's page will continue to be a useful resource for you. Thank you for making these such great events! We look forward to seeing you in 2010...By Alyssa England Sachs, Google Developer Team
Earlier this year we introduced Google Web Elements , an easy way to embed Google products on your site by simply copying and pasting a snippet of code. Today we're excited to announce the addition of three new Web Elements:Translate element here to change your browser's language.Reader element Orkut element Custom Search element themes : The Custom Search element lets visitors search your site (or other content defined by you) and enables you to earn revenue (via AdSense) from highly relevant ads that are displayed in the search results. You've always been able to richly style this element (we described a couple ways in this blog post ), but that required knowing JavaScript and CSS. Now you can adjust the look and feel of the element to better integrate with your site, without having to code anything.Login integration : The Google Web Elements website is now integrated with your Google account. By logging in (if you're not logged in already), you'll be able to more easily select your Calendar, Presentation or Spreadsheet in creating your element. Login is also required to personalize your Reader element.Document selector : Once logged into the Google Web Elements website, you'll be able to easily search through your data when creating a Calendar, Presentation or Spreadsheet element. All you have to do is click the "Choose" button and select the one that you would like to use with your element. You still have the option of pasting in a URL (for instance, if you wish to use a document not associated with your account), but this is no longer required.www.google.com/webelements .By Christine Tsai, Web Elements Team
Google Campfire One we released Google Web Toolkit 2.0 , aiming to do two main things for developers:Make it easier to build faster apps Speed up the overall development cycle Faster Apps Introducing: Performance profiling with Speed Tracer Speed Tracer . Speed Tracer is a performance profiler for Google Chrome that allows developers to see what's going on in a way which hasn't been possible before. We've worked closely with the Webkit community to add instrumentation in the browser to enable developers to gain deep insights into how code behaves, uncovering problems which have been hidden up till now.Introducing: Incremental app download with code splitting developer-guided code splitting . Code splitting allows a developer to split up their application for much, much faster startup times. Imagine if you have a settings page that users go to once a week. Why download that JavaScript when the application starts up? With code splitting, your users download just the JavaScript they need to get started.Faster Development Introducing: Declarative UI with UiBinder UiBinder is a new declarative UI framework in Google Web Toolkit which enables rapid design iteration and a clean separation between presentation layer and application logic.Dive into the details and more features in GWT 2.0.By Andrew Bowers, GWT Product Manager

We've also opened up our brand new gallery , which contains more than 300 extensions!docs and joining our mailing list . You can also check out the videos below:let us know if you want to join us in a small get together tomorrow on our campus in Mountain View (or via VC in New York and Kirkland). Space is limited - we'd love to see many of you there so RSVP early and we'll email you more information if you are selected to attend. You can also meet the team at Add-on Con , where we will participate in a couple of panels.form .By Erik Kay and Aaron Boodman, Google Chrome Software Engineers
Today, we're excited to announce the release of the Google Translator Toolkit Data API. Translator Toolkit is a powerful but easy-to-use editor that enables translators to bring a human touch to machine translation through translation search, bilingual dictionaries, and custom terminology databases. Using Translator Toolkit, you can translate HTML, Word, AdWords, Wikipedia, and other documents in a WYSIWYG ("what-you-see-is-what-you-get") editor, share them with other users, and download their translations onto your desktop. glossaries , and translation memories using the Google Data Protocol . That means that integrating human translation into your translators' workflow just got easier! Here are a few things you can do with the Translator Toolkit API:Automatically connect your content management system (CMS) with Translator Toolkit. You can transform your content into HTML files, protect sections of HTML from translation through the class="notranslate" attribute, upload the HTML files, share the files with your translators, download the translated HTML, and then transform and upload the documents back into your CMS.Automatically connect your file system with Translator Toolkit. You can create a cron job that uploads files into Translator Toolkit, shares the files with your translators, then downloads completed files back to the file system.labs as we rapidly add features based on your feedback. Check out our documentation , where you'll find our Java client library and a developer guide to get you started. Please visit our new developer forum if you have questions.By Mayank Gupta and Paneendra Ba, Google Translator Toolkit Team
Today, as part of our efforts to make the web faster , we are announcing Google Public DNS , a new experimental public DNS resolver. DNS protocol is an important part of the web's infrastructure, serving as the Internet's "phone book". Every time you visit a website, your computer performs a DNS lookup. Complex pages often require multiple DNS lookups before they complete loading. As a result, the average Internet user performs hundreds of DNS lookups each day, that collectively can slow down his or her browsing experience. documentation :Speed: Resolver-side cache misses are one of the primary contributors to sluggish DNS responses. Clever caching techniques can help increase the speed of these responses. Google Public DNS implements prefetching: before the TTL on a record expires, we refresh the record continuously, asychronously and independently of user requests for a large number of popular domains. This allows Google Public DNS to serve many DNS requests in the round trip time it takes a packet to travel to our servers and back. Security: DNS is vulnerable to spoofing attacks that can poison the cache of a nameserver and can route all its users to a malicious website. Until new protocols like DNSSEC get widely adopted, resolvers need to take additional measures to keep their caches secure. Google Public DNS makes it more difficult for attackers to spoof valid responses by randomizing the case of query names and including additional data in its DNS messages. Validity: Google Public DNS complies with the DNS standards and gives the user the exact response his or her computer expects without performing any blocking, filtering, or redirection that may hamper a user's browsing experience. using the Google Public DNS service today, from wherever you are in the world. We plan to share what we learn from this experimental rollout of Google Public DNS with the broader web community and other DNS providers, to improve the browsing experience for Internet users globally.site , read our documentation , and our logging policies . We also look forward to receiving your feedback in our discussion group .By Prem Ramaswami, Public DNS Team
Did you hear that Friend Connect and Twitter are more closely integrated than ever? To learn more, check out our post on the Social Web Blog .By James Reilly, Google Friend Connect Team
Today we're excited to announce our new Google Analytics Asynchronous Tracking Code snippet as an alternative way to track your websites! It provides the following benefits:Faster tracking code load times for your web pages due to improved browser execution Enhanced data collection & accuracy Elimination of tracking errors from dependencies when the JavaScript hasn't fully loaded new tracking snippet :<script type="text/javascript"> HTML5 async specification . Analytics _gaq object . This object acts as a wrapper for the underlying _gat object and executes all the commands, sending data to your Google Analytics account. Your page code can ignore this fact though, because the _gaq.push syntax can be used at any time. See the Asynchronous Tracking Usage Guide for more details.developer docs and get started with our migration guide .By Brian Kuhn, Google Analytics Team
