For the past few days there have been problems accessing the Odoo Help Forum. On my end, it looks like this:

Banner - the odoo forum is unavailable.

And an HTTP 529 status. A few days ago I was getting HTTP 401. I reached out to support about it, and after a brief exchange it turned out that the forum is disabled for all networks except Odoo's internal network. Apparently due to performance issues.

So, if you're wondering whether you did something wrong on the forum and got banned - no. This is a temporary forum issue.
