As of January, 2009, Archive Team no longer considers Yahoo a dependable location for data.
This is not based on their engineering, which has shown itself to be consistent and with few outages. Rather, it appears the company is in relative free-fall with regards to which projects they will maintain and what comes under any given knife for cost-cutting measures.
When a company enters this sort of spiral with regard to one of their core businesses (hosting and providing of information services), and consistently gives little or no indication of their next move, it becomes incumbent upon the users of that service to either demand changes in policy, or find alternatives, even poor ones, and build those up.
Some examples of this new behavior:
- On or about January 27, 2009, with absolutely no notice, Yahoo Pets was shut down, all content removed from the web, and completely redirected under another Yahoo property, Shine. 
Previously, Yahoo showed some level of restraint in how they would shut down services. For example, when Yahoo! Photos, a photo sharing site, was closed in favor of the bright and shiny new property Flickr, it was announced, a special site was provided to assist users in transferring their photos to other sites, and there was an opportunity to purchase an archive CD of your content. . It should be noted, however, that Yahoo! Photos was closed under much protest and duress of the userbase, who in some cases had no interest in transferring to Flickr and wished merely to maintain their own interface.
