Owing to what purports to be a bad outbreak of the BugBear.2 virus on campus, combined with the fact that said virus has been attempting to email random files -- which, on verified occasions, have purportedly included sensitive financial information and the like, the campus sysadmins have decided to put up blocks on the campus network that prevent any computer (except the main campus outgoing-mail servers) from sending mail off-campus.
This means that those of us who use Linux or Unix machines that are their own mail server are suddenly up the creek without being able to communicate.
Do you think there was any sort of announcement about this? Hah. Nothing except a news story about it on the main www.stanford.edu web page, which it not exactly where I'd be looking to hear of a network outage. And we've got system announcement newsgroups, for posting such things.
Sigh. I haven't any idea how long this is going to last. It's been about 10 hours so far, and word on the wires is it will still be there "for some time to come".
