I thought Status Pages or Health Pages is designed to automate the reporting and checking the status automatically. This was my impression when I came across those status pages. Apparently, it is not automated and only update it manually. What is the point of having a status pages if it cannot be automated? I'm sure FAANG and tech conglomerates don't want it to be automated because of SLA.
I'm surprised with FAANG hosted their stuff in their competitors cloud services without providing a fallback cloud service if the primary service is down. Sure it cost money but it would be effective this way than putting all eggs in one basket.
