Port 80 inexplicably working again (lemmy.crimedad.work)

On August 21, my Yunohost server, which I keep in my house, started warning we that port 80 was inaccessible from the Internet. None of my sites use port 80, so everything kept working, but I was concerned because I knew that my Let's Encrypt certificate would fail to automatically renew if I didn't fix the problem. Canyouseeme.org confirmed that the port was inaccessible. Today, with this evening's diagnostic report, my server's warning was gone and Canyouseeme.org confirms that the port is accessible again. I'm pleasantly surprised, but baffled.

Has anyone else run into a similar problem? I am on a residential FiOS connection.

I feel like this is antiquated language in their TOS. It probably dates back to the introduction of broadband residential services, when the cost of delivering network bandwidth was much higher.

But they keep it there as it gives them a nice, ambiguous set of terms they can either hide behind, or use to beat you over the head for a variety of reasons.

I'm guessing they, for whatever reason, temporarily blocked incoming packets going to common ports on your service. Maybe, at some point, the underpaid, overworked network tech on night shift realised they'd inadvertently turned on/off some inbound rule when troubleshooting another customer's problem, and changed it back.

But, you can't complain to them about it because you can't "hOSt a SeRVeR". Bloody ISPs.
