Hi all.

Some of you have probably noticed that the MUUG server was inaccessible from the Internet since sometime last Thursday. This was affecting access not only to the web and FTP services, but also to all the mailman mailing lists. The problem now appears to be resolved!

The U of M campus network has a packet shaper that sits between the internal network and the pipe to the commercial Internet. If it detects too many very heavy traffic flows, it black-lists the host addresses involved. For some reason, this happened to the MUUG server, possibly due to a DoS attempt on it... (We're still investigating.)

Anyway, the networking group has now added the MUUG server to an exceptions list, so this will (hopefully) not happen again.

Sorry for any inconvenience this extended outage may have caused.
