Re: Whats this GUI thingy?
It broke our system in two places:
1. We take a data feed from TfL. That died for five hours so no traffic updates. Nothing we can do as its not our kit, we just consume the data when its there.
2. We then discovered that cdn.leafletjs.com was also down. We use their CDN. That was our fault as we relied on a CDN server being up. Lesson learnt and 15 mins later we were back up.
That was the worst outage we've had and it wasn't our fault, Highly annoying but since we paid exactly 0p for the lot we cannot complain.
I have no doubt that far bigger businesses are talking to Amazon re outages and service penalties. Amazon can use weasel words like "100% error rate" but I'd be gobsmacked if money doesn't start flowing from Amazon to big clients (even if its service credits).
