"From August 22nd to September 8th, European game servers hosted by Valve (L4D/L4D2/TF2/on Xbox and PC) will be offline.



The downtime will only pertain to official Valve servers, leaving the availability of independent clan servers unaffected. Additionally, it will be possible to join official Valve servers from other parts of the world; however, there may be increased latency during this time. "
