Fiber was out all morning, resolved with a reboot of the router. This is what Sonic support said:
Is rebooting your ONT part of your regular maintenance of your fiber connection? How does power cycling an ONT help keep it in "tip top shape"?From a remote stand point, the ONT looks in great condition and that this was a simple need for re-sync. Unfortunately, this something common with almost all modems, with all internet connections types, needing to power cycle is all apart of good maintenance. The only way I see around this would possibly be performing power cycles on your own terms a little more frequently to ensure the modem is tip top shape.
