Every PaaS and IaaS I’ve ever used has had some amount of downtime, often considerably more than 5 minutes, and I’ve run production services on many of them. Plenty of random issues on major cloud providers as well. Certainly plenty of situations with dozens of Twitter posts happening but never any acknowledgement on the AWS status page. Nothing’s perfect.
Yea, when running services where 5 minutes of downtime results in lots of support tickets, you learn to accept that the incident will happen and learn to manage the incident rather than relying that it will never occur.
