Hey all. I'm going to end this project. Mempool is low now. Code is still up if you want to use it. But the truth is that Bitcoin is long term going to be useful only as a backed for the lightning network. With that as the goal of Bitcoin this no longer makes sense to maintain (and pay for).
If you truly need this service message me and I can help you set up something. It's light enough where it can run on a RPI if it doesn't have to handle a ton of transactions.
Also the code is still up
here and if there's some unknown demand for this service I can always start it back up again.
Good luck!
