Twitter down? Hey, it happens, and sometimes it’s even planned! Twitter may be down for planned maintenance tonight – Tuesday, November 17th – sometime between the hours of 11:00 p.m. and 1:00 a.m. Pacific time (2:00 a.m. and 4:00 a.m. Eastern). That said, Twitter isn’t actually planning to be down that entire time – it’s more that they are planning maintenance, and so Twitter could be down at some point during those hours.

“On Tuesday, November 17th, we will be upgrading network equipment between 11p and 1a Pacific,” said a short blurb on the Twitter blog. “The site may be unavailable for short periods in that window.”

So, if you can’t reach Twitter tonight, don’t panic – just try again.
