If this is just a matter of motivation or lack of time I can understand, but if cost is an issue, why not just move to hetzner? A dedicated server there can be had for around 40 bucks, e.g.:<p><pre><code> €42.48 max. per month.
CPU: Intel Core i7-7700
RAM: 64 GB
Drives: 2 x 4.0 TB Enterprise HDD

Thats with unlimited traffic, but no ddos protection or similar, so I don't know how essential that was at DO. Also you're on physical hw which is always more annoying if you have to call in because of a failing disk, but from my years of experience this is as smooth as it gets; shut down the server, open a ticket requesting replacement ASAP and give the drive's SN, and the server will be up again within 20 minutes. Absolutely acceptable for a side-project that doesn't offer anything mission critical. But I'd really be curious what the bill currently is at DO, and maybe you have some monster HW there that can't be matched here. Genuinely curious.
