There was a case like that earlier today for me, my queue was still in the 300's but cyro crashed and my queue insta popped. Chances are a crash happened and you jumped the line.

Agree, I queued yesterday on Vivec, there were around 250 people in the queue, so I decided to go to Battlegrounds. Few seconds after I entered first Battleground I was able to port to Cyrodiil.
