Friday night there will be a move to a new datacenter. Allthough this will be done as 'live migration' there will also be a new IP range.
This will take time to settle in the DNS servers worldwide.
Technically there will be no or hardly any downtime but browser might be pointed to the old location for a few hours. THis should clear up during the night/early morning but please let us know if you have issues on Saturday.
Use https://client.zebra.hosting to make tickets or when the site is down, we have the alternative https://zebrahosting.info to inform you.
