Posting for ideas/advice, if anyone has any, as I'm unsure of where else to turn.
I have a VPS (Named "Bucket") I rent and self host a few services on, along with a home server (Named "Vergil") that lives under my basement stairs and I host many more services on. At 2:01 AM today I got a notification from Bucket that my Plex (hosted on Vergil) was down/unreachable. I'm assuming that's when this issue started.
When investigating I found that Plex wasn't down, but Bucket couldn't reach/talk to Vergil. Further investigation showed that it wasn't just Bucket, but nothing can reach/talk to Vergil. At first I thought it was an issue with my router, as I have my gateway set up in IP bypass mode and manage my network via my third party router (UDM-Pro). But after digging through logs looking for any automated blocks from any misclassified intrusion attempts, I realized that none of my attempts were even reaching the router. So I checked the route, and that's where I found what I think is the problem.
Running mtr
to route from Vergil to Bucket gives full resolution of the route:

Calling the tier 1 support number for AT&T residential support was very less-than-helpful. They kept on wanting to send a tech out to the house claiming there's an issue with the line. I kindly thanked them for their efforts but gave up, and tried emailing the contact email address for the AT&T datacenter/core router from the WHOIS in that last successful hop of the trace from Bucket to Vergil. I doubt I'll hear anything back, but I'm unsure of who else to turn to/what else to try. I've never seen/experienced a route broken in one direction like this. But I'm unable to access any of my devices/services from outside my house, due to it. Hoping someone has an idea or suggestion?
Edit:
Well, after about 38 hours of this issue, the power went out at my house. My networking equipment is on a UPS, so it did not go down. But when the power returned, the route began resolving again, and I am connectable again. Don't know if an area power outage rebooted some AT&T equipment nearby, I would imagine their stuff is also on UPS. But who knows?
For the non-believer about my route previously being complete:
