Tried to do my pvp pet weekly on Sunday, but it wouldn't let me queue. Clicking the "Find battle" button did nothing, then about 10 seconds later I'd get a "Cannot join pet battle queue" message.
Tried again Monday night, still the same. Tried again tonight, and still the same. Looks like I won't be getting my 10 wins this week after all.
Anyone know what is going on? Haven't seen anything official from Blizz, but they usually notify when they have a problem that goes on for this long.
