On puzzle 1564, manually uploading a saved solution fails with the message "timeout due to excessive server load". Closing and reopening the client doesn't help. Closing a 1564 client is slow. Getting the list of shared solutions for puzzle 1564 is also slow, but doesn't time out.
Other puzzles seem to working normally, with no timeouts or unusual delays.
Also, perhaps relatedly, sharing screenshots in chat was slow right after 1564 closed. Chat dropped and reconnected for me an hour or so later, and screenshots seemed to be back to normal.
