There was a massive 1&1 network outage earlier today which affected pretty much all of their dedicated server hosting in the USA and Europe. TTLG was one of the victims from the looks of things.
Edit: 1&1 have a reputation for having cheap hosting but dreadful customer service. Although I have one of their dedicated servers I've never had a real issue since I've managed it myself and never had to rely on their support (other than to tell their sales reps that no, I don't want Exchange server). After the initial problems, the network went down again this evening. According to 1&1 "The problem affects only customers using a 1&1 dedicated, cloud or virtual server." - i.e. those customers who actually pay a reasonable amount of money for their service. Their status page (http://status.1and1.com/) appears to have been written by the Iraqi Information Officer and has reported "All systems functional" throughout the day.
