Update 1.2.3.5 has broken the game for me

Since the last update, I am now seeing the following issues:

• Connecting to the servers when starting the game fails more often than not. I have to restart multiple times to have a chance to get in.
• Matchmaking regularly fails to start. I get the music, the character stands up, but the match does not start. After a while, I get the option to try again.
• Matchmaking also fails at the end of a match. I have to select quit and start matchmaking again.
• There are interface issues. In one case, the menu displayed empty lines. The player action menu from the scoreboard does not work anymore. 

And on top of that, my ping, a very stable 62ms for months, has jumped to 77.

I have checked with my ISP and there is no issues there. I’ve also checked the files integrity, and everything is fine. This update has made the game pretty much unplayable for me, once again an update that break things as much as it improves them…
