It's always a bad sign, always implying unhealty network, overcapacity often (as for now it's probably that), but can't also imply a faulty route at some point.

Until yesterday, once logged in I never experienced any kind of issues expect for the occasional server or duty finder crash. As for now I can't play more than 5mn before getting lag spike ending disconnected, not sure the load bumped a lot since yesterday and today.
