Yahoo! Connectivity Issues

Yahoo announced that the connectivity issues seen a few weeks back have returned as of this morning. They are aware of the problem and are working to reslve the issues. The postmaster team left the following message this morning indicating that they are aware of the issues and working to resolve them:

We're seeing intermittent connectivity issues across our yahoo.com MXes
starting early this morning.

If you are suddenly seeing queues to Yahoo! Mail, please stay tuned for updates
and please refrain (at least for now) from contacting our Postmaster team about
any deferral issues you started experiencing today. We're doing our best to get
this resolved ASAP.

Thanks for your patience,

Carlo
Yahoo! Mail

Mailers should mointor their queues and when seeing large numbers of defferal messages (421's) they should cease mailing and wait four hours before starting to mail again per Yahoo!'s postmaster site. 

Cheers!
