positive about the network timing. pardon my ignorance but what does a t3 hitting up mean?

on another note, we've been having some bad weather here for the last 4 days, the whole time these problems have been happening. well today it was clear, until tonight of course, and the phone system hasn't gone down all day. i'm don't really think that the problem disappeared but it does seem a little strange to me. it hasn't gone this long without having an alarm for the last four days. its just weird...
