The Steam client and related services are currently experiencing connectivity issues following a server outage. The issues affect millions of players worldwide.

Steam users started to experience issues at around 3 PM GMT on Friday December 23rd 2016. At the time of writing the service has been down for almost 45 minutes.

It is unknown when the company expects services to be available again.
