Am running my own router behind the Hub5 (in the DMZ) and it doesn't register an outage in it's logs (which it would do if the Hub was switched off), but we defo have a short stall in connectivity at the time these entries show in the Hub5 log.
Are these kinds of errors something we should be concerned about? Service has been pretty rock-solid for years, other than at the start of first lockdown when there were local congestion issues causing speed issues.
