I had thought about that, but also wondered if repeatedly pinging such things would bring up a firewall rule against me. Even a slow ping rate, but over a long length of time, might be considered abuse. Though, one thing I have against ping tests is that they *only* test a network's response to pings. > If you want to be truly accurate you might ping the ISP router.

I run BIND, so I'm quite certain a DNS failure isn't part of my network notwork problem. Does anyone know what test Firefox uses to determine if you're offline or online? Beyond NetworkManager on our OS raising a flag, Firefox will sometimes decide for itself that you're online or off (and be quite wrong about it). I know the detection can be turned off, for those who use browsers on LANs and don't care about WWW, that detection gets in the way of configuring equipment. But I haven't found anything that explains how it does its trick. -- uname -rsvp Linux 3.10.0-1160.71.1.el7.x86_64 #1 SMP Tue Jun 28 15:37:28 UTC 2022 x86_64 Boilerplate: All unexpected mail to my mailbox is automatically deleted.
