Hit with a 429 for posting a move in the middle of a game?

th0masb commented 11 months ago

In game https://lichess.org/gN0MXA6F I got hit with a 429 for trying to post a move??

What is going on here? Why would I get a 429 when I have just been posting legal moves? It makes no sense to require someone to backoff in the middle of a bullet game. If rate limits would be exceeded don't let the game start...

there was a DDoS yesterday at that exact time, which automatically causes ratelimits to be temporarily tightened all around to protect the infrastructure and the human gameplay

Ok, thanks for looking

@ornicar This happened again... In game https://lichess.org/4SYhq9OP#32. Surely it doesn't make sense to rate limit a game already in progress?
