> There was no obvious pattern to the servers which produced these mystery core dumps. We were getting about one a day on average across our fleet of servers...The probability that an individual server would get a mystery core dump seemed to be very low (about one per ten years of server uptime, assuming they were indeed equally likely for all our servers). Does that tell us that Cloudflare has about 365 * 10 servers in their fleet? I can never quite work out probabilities but I figured they'd have more. EDIT: > all of the mystery core dumps came from servers containing The Intel Xeon E5-2650 v4. This model belongs to the generation of Intel processors that had the codename “Broadwell”, and it’s the only model of that generation that we use in our edge servers, so we simply call these servers Broadwells. The Broadwells made up about a third of our fleet at that time... So at least 3 times the number of servers the above probabilities would suggest, and for edge nodes only. Not sure why I find working out this info fun but there you go.
