Street Fighter V's servers are down for maintenance "indefinitely," bringing a nightmarish launch week to a close.

The servers went offline at 8am AEST / 10am NZDT for a projected three-hour maintenance job, only to have the downtime extended by an hour, and then "indefinitely."

The launch of the fighting sequel has been fraught with issues and complaints from fans, ranging from launch-day crashes and poor matchmaking to network lag and missing features from previous editions.

Arcade Mode has been the most-mourned feature, though Capcom says it is "looking into adding an Arcade Mode."

With a limited scope of offline features, the "indefinite" maintenance of Capcom's servers is looking worse and worse.

Updated 23 February 20:55 NZDT: the Street Fighter V servers are back online.
