Yes they are sharing the same database, but go.epfl.ch is a 1 char shorter than cut.epfl.ch and 2 chars shorter than short.epfl.ch...
Since go.epfl.ch has been rewritten, cut.epfl.ch and short.epfl.ch are redirection to go.epfl.ch. Feel free to use them!

Yes.

URL shortening is a technique in which a URL may be made substantially shorter in length and have more meaning.
Example: https://www.epfl.ch/campus/services/communication/en/audiences-and-channels/epfl-magazine/ becomes https://go.epfl.ch/mag.

Besides from the URL shortening this site has other goals:

• A way to easily remember all complicated URLs
• To have a directory of EPFL's links
• To have a quick and safe (and and corporate compliant) way to shorten URLs

We love them too!

Yes! Since march 2020 go.epfl.ch is an official EPFL service.
It means that it has:

• a name (SVC1207),
• a knowledge base (KB0015277),
• a status page (epfl_service_status),
• and ticket queue (create one).

The first version of go.epfl.ch was a mix between PHURL (https://code.google.com/archive/p/phurl/) with some parts of YOURLS (http://yourls.org/).

Early 2019, Loïc Humbert (an IT apprentice) was asked to refresh the whole system during his end of apprentiship work (called TPI - Travail Pratique Individuel). While still running some parts of YOURLS, the website has been rewritten to the PHP Framework Laravel. The database running go.epfl.ch is PostgreSQL. The whole system is running in containers. The webserver is NGINX behind Træfik.
