You may have noticed problems with [www.swi-prolog.org](http://www.swi-prolog.org). I am doing some reorganization work.

### Plan

- Move services from the VU (Free University Amsterdam) research servers to a commercial cloud server. The VU has kindly hosted our services since about 2008. Thanks! They are modernizing their research platform and the old servers will go soon.
- Use Docker containers for the services to isolate them and make them easier to manage.
- Use HTTPS between the Fastly CDN and backends.
- Some old sites will probably be terminated. Current candidates
  - [pengines.swi-prolog.org](http://pengines.swi-prolog.org) (might make this an alias for [swish.swi-prolog.org](http://swish.swi-prolog.org))
  - [demo.swi-prolog.org](http://demo.swi-prolog.org) (implemented a chat root backend).

### Done

- Main website ([www.swi-prolog.org](http://www.swi-prolog.org)) and [cliopatria.swi-prolog.org](http://cliopatria.swi-prolog.org) are done. Everything is expected to be at it was, except a little faster and with health check that restart the service in case it malfunctions 🙂

### Todo

- [lpn.swi-prolog.org](http://lpn.swi-prolog.org) (broken anyway due to reorganization at main site)
- SWISH
