Re: At DEC's headquarters in Maynard
"With no servers responding, of course, it can't alert him again,"
And that is why you should have an external system monitoring and alerting, not rely on kit on just one site.
Working at BT we were responsible for monitoring all the systems connected to the NHS Messaging Service. As part of this we ran three datacentres that monitored each other plus other third party supplier systems.
When Buncefield oil refinery blew up, our systems alerted that Northgate's Newborn Hearing Screening service had gone offline. As the on-call engineer, I contacted Northgate to find out what had happened. They did have an RFC in place for server upgrades that day but their engineers had been delayed getting to site. This was fortunate for them because their servers were found 3 floors below where they had been.
