Massive spike in latency

Been playing on Onyxia server for a month and so far no issues regarding the ping being too high or lag spikes but suddenly yesterday my ping went up from the usual 120-160ms up to highest was 28k ping which is just insanse. It also keeps disconnecting. Never had this issue previously, looking to get some advice on how to fix or if its a server issue an ETA would be nice

Same. I have ran the game for about a year and have not had connection issues. The past few days I have had incredibly high latency, input lag, and rubber banding. I have done everything in my power to fix the latency issue. I contacted a GM and they said to consult the forums. Please someone help. Thank you.
