We are tracking some intermittent issues with Cloudflare in relation to caching issues we’re seeing due to a recent change that was implemented. This was causing some 502 errors for some of our users. We have rolled back the change and it should be largely clear at this point. If you are still seeing issues, please try clearing your browser cache and trying again. We’ve updated the status site to reflect the issue.
Please let me know if anyone continues to see issues here. Sorry for the inconvenience.
