Yahoo! Instant Messaging recently (from my perspective) had a nearly 2 hour outage. This has brought back a problem we’ve had here a number of times in that we – de facto – standardized on YIM for internal messaging. I’m now trying to encourage everyone (again) to use IRC on our (sort of private) IRC Server.

YIM also has an awesome quirk, that has gotten better and worse, of rather apparently randomly filtering messages, especially messages with URLs according to some scheme only they seem to know.

Another quirk of YIM is sometimes you get queued messages without being told that happened. So the person logs in sometime later and gets stuff you thought they were just ignoring.
