Gmail is down. For those of you who have gmail accounts, which should be all of you, it's been showing a 502 server error since about, oh, a little before 1 p.m. this afternoon.

Valleywag says Google is on it. Let's hope so. In the meantime, don't do anything rash -- like opening up a new Yahoo or Hotmail account. Let;s not go nuts, folks.

Update: It's back up.
