We deployed a new version of PythonAnywhere this morning. Everything went pretty smoothly; there were a few problems with some hosted websites shortly afterwards (an error in a load-distribution algorithm put too many websites on some servers, and not enough on others) but some sharp-eye customers spotted the problem and let us know, and we were able to rebalance things and fix the issue quickly.
There are a couple of great new features in the new system, but we're doing some last-minute testing before making them live -- watch this space for more information :-)
