Thank you for your suggestions, we definitely agree with you that we need to be better about sending/posting notifications when outages occur.
We do have network technicians on call for when equipment fails or something that would be visible on our systems. However, the issue we have been facing recently is that there have been short power outages in some areas and when everyone's equipment comes back online at the same time, it overloads our DHCP servers and freezes everyone's connection.
In this case, everything on paper is showing up as working "as normal" on our side, but in reality nobody can get online due to the huge traffic jam on the network. Then because it's after hours, we aren't receiving calls from customers reporting problems, so it makes things even worse.
Due to these issues, we have been working with our equipment vendor to come up with solutions to prevent this issue from happening further and have come up with added precautions ourselves to be more attentive and proactive about these outages in the future.
I'm very sorry about any inconveniences the recent outages have caused!
