In-Game Chat went down at about 12:30 eastern standard time
It probably didn’t, your client-side data likely just shat itself, as it’s prone to doing. Try reloading the game by reloading the webpage, that usually fixes it for most people.
Was happening to me the other day when someone was spamming chat every second. Just reload the page and it fixes it.
Ahh, it hasn’t happened to me yet, so I thought the entire thing went down. Thanks!
