Thanks for those links have bookmarked.
I called Enta support and that was the explanation given. Followed up with a ticket to Vivaciti which said they saw a lot of unprecedented traffic this morning and Enta peers with MS.
I have never seen my connection go down to 1 meg before except on ADSL Max with Zen. Funny thing is as I was doing speedtests I saw my graph peak at max for a second then rapidly come down and settle at 1-2 meg as if it was being shaped not congested. But the guy at Enta said traffic was coming down and my speeds should return to normal with a few hours and they did.
Looking at those graphs there is no peak at 8am-12pm when I was pretty slow unless it was a DDOS on Enta, and nothing on the Enta NOC pages. Back to normal now but I would love to know where all the traffic was from, my Windows Updates were pretty small, even for Win 10.
