Subj: [moderatorcentral] Planned Outage: Wednesday, July 8

On Wednesday, July 8th we will be performing scheduled maintenance on
the Yahoo! Groups databases. During this time, some of you may not be
able to access your groups, and group mail will be delayed.

Maintenance should take roughly two hours, and will begin at 1pm PT
(8pm UTC- to determine what time the outage will take place in your
neighborhood, please visit this link:

Once the maintenance has been completed, we will update the Yahoo!
Groups blog (http://www.ygroupsblog.com).

Thanks for your patience!
