Fios Internet Keeps Disconnecting

I am encountering a strange issue with my Fios internet. Starting yesterday I have noticed that my internet cuts out every few hours. Although it is down for a minute, it is very disruptive as it occurs while I am in meetings.

I have tried things such as restarting the router and ONT with no success. Looking through the router's System Logs, I see the following message each time the internet goes down:

[SYS.6][SYS] Reboot by Power Cycle/Software Fault induced

What I find odd is the time in which these messages occur. There is clearly a pattern:

2025 Jan 11 19:07:25

2025 Jan 11 17:43:07

2025 Jan 11 16:06:58

2025 Jan 11 14:06:21

2025 Jan 11 12:06:16

2025 Jan 11 10:06:14

.....

2025 Jan 10 22:06:37

2025 Jan 10 20:21:01

Any ideas?

Providing an update in case someone may find this helpful in the future. I performed a Factory Reset of my Fios router and restored my old configuration settings. This appears to have fixed the issue and I am no longer getting those system log messages.

We're getting the same thing here in Albany, NY.

In my case i have no Verizon router (I use my own). But all the other neighbors are also having the same issue.

I'm in Clifton Park, NY so just a bit north of Albany. I've been also having this problem for a couple of days now. My Fios installation is only ~3 months old, so I've tentatively held on to my spectrum cable connection as well which has proven to be invaluable while this is happening. I'm uncertain what to do next as contacting fios support just lead to the tech saying that the signals looked fine off the ONT so there was nothing that they could do.

If you are getting the [SYS] Reboot by Power Cycle/Software Fault induced you may want to try doing a Factory Reset of your router. That is what fixed the issue for me. If you have a spare router you can also try using that.

Used my own router, used the verizon provided router, same thing happens regardless. The fact that I keep getting new IP addresses (that are in different class A network ranges), and not renewing my previously established dhcp lease, makes me think that something is just very wrong with their dhcp server upstream.

Also in Clifton Park and also experiencing the same thing for 2 days now.
Confirmed with at least one neighbor who is also experiencing this.
Clearly an issue.

FWIW I spent about an hour with Verizon support chat. Talked to two people, shared the link to this chat, and confirmed with neighbors who have noticed the same issue in Clifton Park.
In the time I spent with Verizon support they remotely rebooted my ONT twice and added Disney+ to my account w/o my permission.

I am trying to figure out how to escalate to a real network engineering team at Verizon.

Man if you can figure out how to get to a real team that would be appreciated. I was told by someone on the phone to wait until Monday to open a new ticket (?????). I'm not sure how that's an acceptable answer. I'll give the chat option a try tomorrow as I feel like the phone support people are just trying to get off the phone as quickly as possible, resolution or not.
