The Internet Archive discovers and captures web pages through many different web crawls.
At any given time several distinct crawls are running, some for months, and some every day or longer.

This collection contains web crawls performed as the post-inauguration crawl for part of the End of Term Web Archive, a collaborative project that aims to preserve the U.S. federal government web presence at each change of administration. Content includes publicly-accessible government websites hosted on .gov, .mil, and relevant non-.gov domains, as well as government social media materials. The web archiving was performed in the Winter of 2016 and Spring of 2017 to capture websites after the January 20, 2017 inauguration. For more information, see http://eotarchive.cdlib.org/.
1/12/2017: CDF version V18.104.22.168 is
released. This release, with a minor change to the earlier release of V22.214.171.124,
includes a new leap second added for 1/1/2017. Please read the change
note that describes the changes made in
this release, as well as all previous releases.
We have received questions about users getting warnings of incorrect
CDF_TIME_TT2000 times in CDFs
written with an out-dated leap second table. Previous CDF versions, till
126.96.36.199, leave the CDF header for the
leap-second-last-updated field to the value inserted when the CDF was
created. It turns out that this is a problem when adding additional data or
when copying an empty (master) CDF for filling with data, since the resulting
CDF carries the initial, out-dated leap-second-last-updated header and will cause
warnings when opening the CDF by the newer CDF version with a newly added leap
second. We have addressed this issue in this version, which will automatically
update this header to the newest leap second date, if there is a new
leap second added, when writing/updating TT2000 data to the CDFs.
You can check the leap-second-last-updated header in your master file by running
cdfdump tool command and searching for LeapSecondLastUpdated
cdfdump -dump metadata <CDF master>
In case you need to update this header to the latest leap second date,
cdfconvert tool command can do that:
