AWS’s US-East 1 continues to be the Achilles heel of the Internet. And while yes building across multiple regions and AZs is a thing, AWS has had a string of issues where US-East 1 has broader impacts, which makes things far less redundant and resilient than AWS implies.
People say this, but this this was just a single AZ, and in the last 3 years of running my startup mostly out of use-1, and we've only had one regional outage, and even that was partial, with most instances uneffected. And honestly, everybody else's stuff is in use-1, so at least your failures are correlated with your customers lol.
Is it not a selling point to be able to say "we're still up while out competitors are down"?
