Multiple outages most days, usually ~8 minutes long [SOLVED]
After months of solid reliable service my business internet has been experiencing outages almost every day, often multiple a day. Many of them last about 8 minutes, some are shorter (occasionally longer). I've had a service technician out, he replaced some older connectors and the modem, which improved the smaller outages somewhat, but the longer ones have continued.
I've been measuring connectivity between my firewall and the "next hop" router upstream of the cable modem, here's what I have recorded:
In the last 3 weeks:
2/14 - 2/20 - Outages over a minute long on 6 days, 5 outages of 7-9 minutes, total of 59 minutes of outage.
2/21 - 2/27 - Outages over a minute long on 5 days, 6 outages of 8-10 minutes, one outage of 35 minutes, total of 91 minutes of outage.
2/28 - 3/04 (so far) - Outages over a minute long on 5 days. 6 outages of 8-10 minutes, total of 66 minutes outage (so far)
Sometimes the status page will eventually acknowledge there's an issue (usually right around the time it recovers), often it doesn't.
Internet troubleshooting can never restart my modem.
The technician who came out was very helpful, but did not seem to have access to any logs for the history of infrastructure issues in the area (Concord/Walnut Creek CA), this doesn't seem like an issue within my facility (If it was, i'd be happy to get that repaired), but a local or regional problem. This is extremely disruptive especially given the amount of business conducted virtually.
I'm looking for any kind of contact to at least acknowledge the problem and provide some kind of status - as I noted before until recently (even through most of the COVID lockdown) my service was excellent.
Any suggestions on contacts or troubleshooting steps are welcome.
Update: The underlying cause was a failed amplifier on the line down the street. Once Comcast/XFinity acknowledge there was a "network issue" it got resolved very quickly, but it took a long time to get to that point since the presumption is that it's a single customer problem.
