Random spike in ping

[Roberatwand]

I play alot of Oldschool runescape and I've noticed recently that I'll get random changes in ping due to what I can presume is bad routing, it happens randomly and unexpectedly. Normal servers close to me I get 40 ping to I'll end up having 110 ping (wouldn't be an issue if Jagex US east servers weren't shit.) because my connection will route me to Las Vegas for some odd reason. Now I'm having issues with the British servers that I normally have 110-120 ping on I'm getting over 150 ping which is closer to my experience on a German server. Was curious if anyone was able to help with this issue to prevent or give a fix for when it occurs.

There is nothing that you can do tbh, there is something wrong at the ISP level. Best option is contact them and tell them your issue
