UPDATE April 12th:
We are blocked at 30.000 simultaneous players for 3 days now. The main reason is that the component which is recording our game results is taking an average 300 milliseconds by game.
There are much things to do when we are recording a game results, like computing and updating your ELO, recording the game statistics and various other statistics, make you available in the lobby again, ...
300 milliseconds looks fast, but we have 200.000 games played on BGA everyday now, and this is one game every 430 milliseconds ... and way more at peak hour.
As a consequence: sometimes, you are "blocked" at the latest table you played, because we are processing the "queue" of the games results waiting to be recorded. This is not satisfactory and that's why we cannot go upper than 30k at the moment despite our servers can host more than 30k players.
We are optimizing this component at now, and hope to divide the processing time by at least 3.
In addition, we are going to add 4 more servers to the infrastructure in the 3 next days, to get some extra power.
Hopefully, if we do not met another issue like the one described above, in one week from now we should have slightly increased the capacity.
