Over the past few days our infrastructure has been experiencing some technical issues that our team is actively investigating and looking to resolve. During this time, server join and spawning is functioning, but at times may not be reliable. Following any attempt to spawn a server via Create Match, please review the top of your server browser to verify whether your match successfully launched before trying again.
Please follow us on twitter to stay up-to-date with the latest developments: https://twitter.com/quakelive
As noted there, once we feel that we have fully resolved the issue we will extend the expiration dates of our subscribers to credit them for the interruption of service. We’re sorry for any trouble that may arise and appreciate your patience.
