Various software used to hardcode 1a, so 1a received disproportionate load. Now, everyone's a-e is randomized among the "true" a-e, meaning that even if everyone hardcodes 1a, the load will still be evenly distributed.
The AWS status page[1] is showing problems for EC2 East as of a few minutes ago. This might be is a more widespread issue. EDIT: Various non-Heroku EC2-East-based sites (e.g. Quora) seem to be down as well, lending more evidence to this being an EC2/EBS outage. 1: http://status.aws.amazon.com/
Half the startup world is offline right now, yet the AWS status page is all greens with one "info" notice about EBS (which I doubt is the issue here). I'm glad to have moved off a fully AWS stack back to my own servers over a year ago. My uptime, bills, and stress level are all much improved.
Their uptime percentage is 99.97%, but I'm having a hard time fighting the recency effect that is telling me to get off the platform ASAP.
I just got up (it's morning in Israel), and a client of mine in the US with a major, mission-critical application was screaming (rightly so) that things are down. We're already looking into alternatives -- perhaps not leaving Heroku altogether, but certainly not depending on them 100 percent. There's no way that we can entrust the business to something that can just catastrophically fail at any moment. I've been runn…
Dont overreact... heroku is using AWS which is down for many other sites right now other than heroku. This is an EBS issue that is occurring.

Definitely an EBS issue. Our (EBS backed, Heroku hosted) DB was returning queries more and more slowly leading up to the outage.

I know AWS EC2 does support multiple global regions and within each region multiple availability zones. You're supposed to host your application across more than one AZ if you want good fault tolerance. Not sure if Heroku uses this though.
And yet we continue to throw everything on AWS... You know there are OTHER data centers, right?
Other datacenters can go down, too. In many cases, the complexity of running an application across different platforms (say, AWS + Rackspace Cloud) might not be worth it.
