Starting today, I noticed that posting a comment takes upwards of 2-3 minutes until it's committed (the "reply" button is turning round and round for a long time). Is there something wrong with the servers or some sort of moderation? Not sure what's going on or why.
Happened to me as well today. Except that I didn't wait for that long but opened a new browser tab and saw that the post was posted. Closed the other tab which, slightly surprising, gave no warning.
