Our hosting providers at Compute Canada are upgrading their cloud infrastructure which may cause brief 10 minute network outages for some of our servers between 3/24 11AM EDT and 3/26 11 AM EDT.
If you encounter any issues with our servers during this time it might be a good time go take a walk, make some coffee, etc. 
Apologies for the inconvenience, and if you encounter any other issues please let us know here or on twitter.
