Short (1-5min) Internet drop at 4am PST every morning, consistently.

 I don't know if this is something like my IP address getting refreshed or if some maintenance happens, but it's totally unacceptable when I do in fact work through mornings and have a 1-10 minute internet drop that seems to have no factors to it or consistency in what I'm doing other than it being 4am.

Thank you if you took the time to help.
