This Friday, June 8th at 9 PM PDT (that’s 4 AM GMT Saturday morning) we’ll be doing a site upgrade. We expect this will be complete within 30 minutes, during which time Wikispaces will be offline.

As always, we keep track of maintenance happenings and problems with the service at an off-site status page:

http://status.wikispaces.com/

It’s a good place to check if you ever have trouble getting to Wikispaces. There’s also an RSS feed if you’d like to keep up with changes as they happen.
