Starting in 1996, Alexa Internet has been donating their crawl data to the Internet Archive. Flowing in every day, these data are added to the Wayback Machine after an embargo period.

Ping Server Services - Ping Server from VeriSign, Inc.
Weblogs.com®, a VeriSign service, is a ping server
that automatically notifies subscribers when new content is posted to
a Web site or blog. Weblogs.com receives millions of pings every day
from blogs that configure their publishing software to notify Weblogs.com
the moment content is published.
The VeriSign-operated Weblogs.com ping server will
continue to operate as an openly available service, which benefits the
entire blog community:
Blog publishers
can immediately notify the community when new posts are available.
Anyone can openly
monitor the updated posts, enabling a wide range of intelligent blog
monitoring tools and applications.
VeriSign acquired the assets of Weblogs.com in October
of 2005 from Dave Winer, one of the founders of RSS (“Really Simple
Syndication”). By migrating Weblogs.com’s pings to VeriSign’s more robust
and scalable infrastructure, VeriSign offers the users of feed updates
a more reliable and intelligent platform.
More information about the Weblogs.com ping server
can be found at www.weblogs.com.
