Apparent scheduled outage?

The tech support people think I’m crazy.!

Is anyone else having an issue with Century Link’s internet going out at 8:30 pm and then coming back up 10 to 15 minutes later? Before the time change it was happening at 7:30 pm. This has been happening every night since December. One of my neighbors said they had it happen too.

It wasn’t an issue for me until the time change and since Sunday it interferes with an evening online zoom meeting so I need it to stop.

When I called support on Monday, I was told it was my old modem. Set up a new modem they sent me new modem yesterday and it happened again right on schedule. Must not be the modem. Spent three hours last night texting with support and they couldn’t even acknowledge what I was telling them my problem was. Thinking this might be a system issue. Anyone this is happening to?

I finally got a ticket and a service call scheduled for tomorrow. Looking for things for the tech to consider. Thanks!
