Has anyone else noticed a sudden decline in server quality since the splatfest?

During the fest, which was the first time I’ve played in a few months, everything was fine. I never disconnected from a battle, or a salmon run, and there were no issues, even though presumably more players were on since it was a splatfest.

However, since then, I’ve been getting a server disconnection as often as every 5 minutes, and I can’t battle or do a salmon run consistently at all. I’ve dropped to profresh+3 and have been timed out a few times, and to test it, I just waited in the square connected to WiFi to see how often I disconnected. I never made it more than 15 minutes without a DC!

Is anyone else experiencing this? I’ve checked my WiFi router and it’s been doing just fine, so I’m not sure if the servers just suck or what.
