The systems are all back online.
The maintenance, which really wasn't maintenance at all, but rather a move of all our infrastructure from AWS in Ireland, to Hetzner in Germany.
The policies will be updated soon, to reflect this. There is still some backup data at AWS, which will be purged soon.
Also, we will continue to use AWS S3 for some transient storage.
All databases and all processing of data is now conducted on our "own" systems hosted at Hetzner.
This has given us significant more computing resources as well as cost savings.
More importantly, we have upgraded the setup, in almost every way possible, allowing much smoother deployment of changes, as well as much more control and insight of operations.
The coming week or two, will likely call for some fine tuning and tweaking, but all in all, it looks like everything is running smoothly.
