It's gotten a little better since launch atleast for me. It still crashes quite a bit but i've noticed not as frequent and the siege pops seem to be quicker. At launch it was 10 min queue-crash-10-15 min queue etc etc.
I notice the siege server crashes way more often than the other types. It usually crashes right at the end of the warm up period or right at the end when things get heavy.

For me, Siege server stability has gotten worse. Most games kick me out with "connection timed out" before I can even join. Haven't played a full Siege match in a week or so.
