Same here so you're note alone. Also two of the russian nodes I frequently use are down.

Which mudfish nodes did you picked?  Please try to pick one manually based on FAQ - Nodes secion.

Hello, yes I tried using multiple direct nodes. They all suck recently. I usually had ping of 180-200. Now I have 280-300. Something really broke. In fact, with single node choices Ping is terrible (The 280-300). With Duo node mode ping is a lot better (around 200) however there seems to be an issue with the connection between the nodes. It keeps timing out (going to 3000 RTT) and that is why its currently not working properly.

Its so bad now... Even a direct connection to the Japan nodes keeps spiking out. Please fix this.

Weird... Then did you try to change Connection Protocols to TCP based and test?
