It started up again so I had a tech come out it was a filter in the line so all this time it was a filter the tech pulled out :(.
I'm also having this issue on gigabit, started about a week ago. I had a tech out today who made some minor cabling/tap changes which improved upload speeds, but after a modem reboot it was good for a few minutes then right back to 30mbps or less(which is what happens every time I reboot the modem). He said(and showed me the notice in his dispatch app) that there is a "national degradation of services" that has been going on for about a week and they have no estimation on a time for it to be fixed.
FYI for everyone having issues, there are a few things you can do on your side to try and address the issue. Replace cable wires, replace splitters, verify all connections are snug. DON'T wrench them tight, that can damage the connection if you do it too tight.
Also, believe it or not, try changing the electrical connection to a different socket. That can sometimes help as well.
