Thank you for contacting us. I am sorry to hear your service is down. There does appear to be an outage at the Flagstaff gateway in Arizona, which is the gateway that was assigned to you during installation. Our engineers are working hard to recover this and have made progress so far as some customers are able to access their service again. We do not have an estimated time frame for how long this will take to be completely resolved. These events usually take 1-2 days to be resolved. If for some reason this happens to take longer, I will credit your account for this missed days of service. I apologize for the inconvenience.
It may be related to bad weather at your location or at the location of your gateway. Have you tried rebooting the modem?
Hang in there; I'm sure someone here will give you more complete advice.
Where is your gateway, though? There could be issues there. Edit: If you don't know how to identify your gateway, see this tutorial: https://chucksbasix.com/2017/10/06/how-to-find-your-hughesnet-gateway/
There may be an outage at the gateway; if so, there will likely be an announcement. Check HN's social media sites (Twitter, FB).
