Just checked my Flightaware stats and saw that all 3 of my feeders have been off line for 6 hours. I also checked a few of my local feeders and they are all off too. However, abcd567 and others in Canada are OK.
[Edit] I just checked 5 minutes later and all seems to be OK
Something ingesting I noticed after I got the link back and looking at the stats page a few feeders continued to work during the outage unlike @g7pnu, @triggers and my feeder.
Could it be down to ISP links or DNS choice that kept them feeding through the 4hour outage?
