I have been load testing our server solution, and also testing playfab scaling. I recently started sending thousands of players at a time for matchmaking (which is expected at launch), and it has been going well for several days, until last night.
I started getting 500 errors from the CreateMatchmakingTicket endpoint, randomly. At first I thought maybe Playfab was upset with my IP and rate limiting me, but I’d expect a different response for rate limiting than 500. And like I said I've been doing these tests for a while with no issue.
I also started running the requests manually one at a time (slowly), and some go through, some return an error.
Here's some data from the http responses that hopefully an admin can look up:
