Why do I have 100 + ms ping today?

Normally I get around 30 ms it was 30-35 yesterday, I ran speedtest just now and my ping to isp servers is 9ms. So why am I today getting such high ping as high as 130 at times.

because blizzard is too incompetent to get their stuff sorted. I guess youre playing in eu, then your traffic gets routed through us servers for absolutely no reason.

Its funny how they cant even look into it themself but tell users they have to prove it - then they dont even believe a single user but require multiple users to prove it before doing anything about it.

If I could even start the game I would put up the required data, but I cant even launch the battle.net launcher, hell after uninstalling it I cant even install it again.
