7Sage will be temporarily unavailable while we are upgrading the servers.

PDT: 11pm Saturday, July 17 late night

EDT: 2am Sunday, July 18 early morning

We expect that the site will be available again within an hour. But even if things go sideways, it will definitely be back online by the next morning.

Please avoid doing a PrepTest or Problem Set near this time so that your work is not interrupted. Sorry for any inconvenience!

Edit: Maintenance is complete. Total downtime 40m. Thanks!
