According to the 5th Report and Order, can I ask for waiver from monitoring IPAWS server?

Yes. There is a provision for stations in severe situations, such as where there is no high speed Internet. However, stations (1) must file for a wavier, (2) have a substantial “story,” and (3) realize it is a high hurdle to get a wavier – according to the FCC, waivers will be hard to get.
