Definitely speed. My ISP runs on another service providers hardware and it bugs out from time to time and I get 1/10th of the speeds I usually have. My ISP has no way of knowing this so I have to know when it happens and place a ticket so they can place a ticket on the hardware guys.
This is from July 11th. Nothing new as of now that I’ve seen.
But closer to October we should be on the lookout.
