Overnight Flighaware started showing that my Pi ADS receiver was offline. Web portal shows offline, but the PiAware portal shows it running ok and sending data.
When I checked the local page at IP:8754, it’s showing a Disconnected (http_error:503) status for the FR24 Link.
Any ideas what could be causing this?
A 503 error indicates that the remote server isn’t reachable.
Either the server is down of overloaded with traffic, there are a lot of reasons why you get a 503 error.
I had the same issue on 3 of my sites but meanwhile they are all back-up again.
Since there is/was a big issue with PHP today all over the world my guess would be that there was a lot of traffic towards the sites in general.
If you want to read more on that see this link as one of the many examples:
I’ve seen loads of websites being taken offline today I suspect that was also the case for some intermediate servers or even FR24 servers (but I can’t be sure since I don’t know if they run PHP). 70% of the websites worldwide run it so I wouldn’t be surprised.
Thank you for the reply and information. Looks like whatever the issue was, it’s resolved now and Flightaware is showing as online.
For part of the morning and afternoon, I received a notification on my status page: "Site 228596
If the issue persistant then it might be correlated to a network issue somewhere upstream, so it isn’t always inside your span of control (your own network) .
Usually the percentage message is a temporary hickup in the traffic routing towards the server.
