Boo. Such a shame. Of all the PaaS offerings Ep.io was the one I was really rooting for. There was a real personal feel to the service - support email repies from Andrew directly, and an always active IRC channel.
PaaS sounds like it could make my life so much simpler. I've tried out Ep.io, Heroku and DotCloud, and have test apps continuing to run in all of them but none of them are quite right yet for me to trust a client's production site in, so I'm yet another person replicating using Linode VPSs and a custom build and provisioning script.
Best of luck to all involved with Ep.io, and it's commendable to see their dignified plan including working with helping their customers move away to other services.
