This past Sunday we performed a major upgrade to our hardware (to prepare for the increased usage for the upcoming school year), but it appears there are some problems with the new setup. We are working diligently to figure out what’s going on, and in the meantime we apologize for any brief service interruptions you may experience.
We will post an update on the blog as soon as we figure out (and fix) the cause of these service interruptions. Sorry about this, but rest assured we are working to fix any issues.
