The FCC currently says that stations may just put “Did not receive RWT from IPAWS” or some such notation. There is no urgent need to search out and log the reason. If are alerted to any missing tests, we will note them on our website.
FEMA has no plans to post problems/errors on any website. Their main concern is that you have a “connected” status. Beyond that, they will distribute information as available, but not necessarily on any schedule.
