Reliability: It’s not great

I remain kind of amazed about how heroku managed to pull off what they pulled off, in the first case.

Also:

> The Heroku exodus broke our assumptions. Pre-Heroku, most of the apps we were running were spread across regions. And: we were growing about 15% per month. But post-Heroku, we got a huge influx of apps in just a few hot spots — and at 30% per month.

I hadn't before seen anyone with a big picture view confirm a heroku exodus was happening, although a lot of people suspected it or had anecdotes.

But if fly is seeing a pretty enormous number of customers moving from heroku to fly... oh wait, now I'm wondering, is this mainly a result of heroku ending free services, and those are free customers coming to fly for free services?

If so... that's a pretty big burden to take on without revenue to match, it does seem kind of dangerous for fly.

Heroku was built on top of AWS. They didn't have to handle many of the hard problems Fly does.

Do they unpack what the 30% includes? Is that revenue, VMs, accounts?
