[luatex] Server upgrade planned for Feb. 1

[Taco Hoekwater]

Hi all,

We plan to upgrade the software installation on the zapf.ntg.nl server on Friday Feb 1, 2019.

As a consequence, various tex-related sites including www.ntg.nl, wiki.contextgarden.net 
and www.luatex.org, as well as the mailman lists @ntg.nl, will be down for some as-of-yet 
undetermined amount of time. 

We’ll try to be fast, but one never knows with these things...

Best wishes,
Taco
