I just called 1and1 tech support. No ETA yet…they are hoping to have the issue resolved within 12-24 hours. “Hoping” is the operative word here.
According to the 1and1 support rep, this was not a planned outage, so they could not have alerted customers in advance. He also said something about having to reboot servers, but he had no other specifics on the problem at this time.
Standing by…
