High world ms world of warcraft

Yes but unfortunately a huge amount of people are having this issue at the moment and Blizzard’s only response was “Contact you ISP” even though many people have and their ISP said there were no issues on their end and no other game seems to be effected except WoW. It’s been almost a month now that the game has been unplayable for me and numerous others have been having issues for longer. Still no assistance being offered though.
