Wow, I have to admit that I have not heard anyone in the past 2 years or so to be on Heroku so it makes sense. I think they handled it quite well knowing that there most likely have been a steady decline of users.

Generally I would avoid promoting myself but in this situation I think it fits the topic. I'm co-founder of a Platform-as-a-Service based in Europe named Ploi Cloud [0]. We focus on web applications working on NodeJS and PHP but would be open to other platforms if people need it. Heroku has always been a source of inspiration to me so if you are looking for an alternative and care about it having a strong European presence please check it out. (We do have a US location too!)
