The earlier network issues experienced on the Microsoft Update platform,
which delayed the October security updates released today, have been
addressed. The October security updates have been been replicating as of
approx. 3:00pm today PST.
If you had a scheduled WSUS synchronization earlier today, which did not
contain October security update metadata, you can kick off a manual
synchronization or wait until your next scheduled synchronization time to
recieve these updates.
To reiterate messaging on the MSRC blog (http://blogs.technet.com/msrc/archive/2006/10.aspx) this delay was due to networking for these systems: there are no issues with the October security updates themselves. Also, this issue doesn't affect customers using Software Update
Services (SUS), Windows Update v4 or Office Update.
