I am a feeder and have unlimited alerts. I had well over a 100 flights and tail numbers entered. They are all gone and I don’t have a backup. It’s extremely frustrating to reenter what I can remember. I work at a remote site that fuels aircraft and these alerts come in handy as some planes just randomly show up.
Here is their response to the incident.
"Thank you for contacting FlightAware. It appears an issue on our side cause the alerts tied to the AdakAlaska account to disappear. This does not terminate your privileges of creating unlimited alerts as an ADSB feeder. The alerts unfortunately will have to be recreated manually.
We apologize for any inconvenience this may cause"
If there is a way to back up please do so.
