ping issue

hey im connecting from iran and lately ive had a serious problem with ping connecting to wow servers ( hosted in ovhcloud ).
any game i play i have pretty good ping beside wow pservers and its fluctuates like crazy. like sometimes i have normal ping but then it can fluctuate between 200-2000. and basically made it unplayable for me.
when i ping warmane in cmd it shows me normal ping i had before which is about 90-100 ms.
but only when i login it starts to go up.
ive tried different DNS routes and even changed my isp 3 times already but cant get any results.
a friend of mine told me that its bec ovhcloud is being used for illegal vpn creators so government and ovhcloud having issues with each other.
what can i do to fix my ping, ive used vpns before and got banned for using them so idk what can i do
