Wasn't sure if I should make a new thread or not since I saw other people with the same issue but better to be safe than sorry.
For the last few days I've been getting frequent disconnects while playing games that run through blizzards battle.net (world of warcraft, heroes of the storm and overwatch to be more exact) as well as the website itself in these periods. I don't have exact times for the disconnects but they're definitely frequent enough to be noticeable. It also only occurs with blizzard games as I'm able to play other games fine and during the blackouts I can use other websites fine.
I've gone through all blizzards troubleshooting and been pointed to my ISP. Thanks for your time and I'll try to keep not of the exact times it occurs.
