I'm starting to think so too but its very hard to test as an end user. I connected without router (PPPOE) from PC but that was way worse:Unfortunately wasn't home to check but will be today.
Mist's line seems to be cutting out completely on the regular... what heck is that about - doesn't look like normal congestion, perhaps Frogfoot hardware on the fritz?

Besides the line just cutting out randomly mid online game, the fiber is performing very good. But it has gotten to the point where i wish i didn't switch to fiber, its just so frustrating trying to get any support.
