It is a sad day.
Where are you moving your side projects?
EDIT: I'm asking since I have no idea where I should go next. Heroku was a blessing.
I had a good experience there, but it's a lot different from Heroku. There's no paid support or anything.
Also the cost of your existing dynos may not change if they grandfather and not change running dynos' prices. Who knows until they actually announce any price changes.
ps : I dont work for them
