Small update on this.

Over the past 3 months, I have slowly familiarised myself with the tiles.wmflabs.org and I have now migrated rendering and serving of these tiles to a new server. I still need to do some work on the following things:

1: tile expiration

2: puppet deployment

3: log collection/rotation

4: renderd logging

5: renderd socket getting stuck ?

wma.wmflabs.org is still not saved however.

This is just another small reminder that, because the servers which host tiles.wmflabs.org and wma.wmflabs.org (wikiminiatlas) and overpass-wiki run on a version of the OS (Ubuntu Trusty) that is no longer supported (and hasn't been available for new instances since november 2017).

These services need maintainers and support by community members in order to keep them alive after dec 18th (after which wmflabs will phase out those versions) and before the EOL of early 2019 of the OS. Unfortunately it seems no one is stepping up so far to convert these machines.

As I was curious, I looked around on the tile server a bit and used what I could find to update

This is all the information that I could gather, but i'm FAR from sure if that is complete information and if I would break anything with a rebuild basing myself on that info, so any information on missing elements etc. would be appreciated. I've not gotten around to looking at wikiminiatlas.

If the services are not rebuild then likely they will just disappear at some point for all layer variants. This includes the mapnik, black and white, hill shading, hike bike layers. As I have no idea how many users of these services there are, it is hard to say what the effect of that would be.
