It's very annoying when Twitterfeed is down. This is an account which is responsible for a whole bunch of auto-tweets into a whole bunch of Twitter profiles.
Twitterfeed recently took cash from Betaworks - investors in both Bit.ly and Twitter. They alo launched a redesigned site just recently.
It's a shame to see them offline. I use verisign (old skool!) to login. Perhaps the snaffu is in that mechanism.
