A quick update on freeCodeCamp's servers

Hey everyone, thanks for your patience with our servers. Here’s what happened, what we’ve learned from the experience: https://www.freecodecamp.org/news/freecodecamp-servers-update-october-2019/ You can use /learn without signing in. If you insist on signing in anyway so that you can save your progress, try this method. We did a database backup before we started maintenance on Tuesday, so your data should be fine. This forum, news, and our YouTube still work fine.
