Fortnite updates are updated every alternate Tuesday. These updates are first posted on the official Fortnite Status twitter page. Moreover, if there is any emergency downtime, that will also be listed.
When will Fortnite be restored?What is the typical downtime in Fortnite?
It's very difficult to put a precise number on it because not all patches are the same in terms of size. However, Fortnite downtimes usually finish within 90-120 minutes of the servers being removed offline. Season launches may take longer, but that's dependent on the amount of the update itself.
Matchmaking is disabled 30 minutes before the update goes live, as previously mentioned. However, to be able to play Fortnite again, you will have to wait till your system finishes downloading the patch.
