To anyone who plays on the western European servers, they have vast experience in the sea of technical issues that arise and affect the play on those servers.

After frequent outages and lag problems, including some major ones on April 5th which caused major issues, the servers will finally be entirely updated with the infrastructure receiving an overhaul.

Riottmx on the issue:
“On Friday 5th April we hit some large scale problems on the hardware side, this caused major issues across several platforms, and rather than simply replace the faulty device, we’ve decided to use this opportunity to upgrade our European infrastructure in Frankfurt. This work will not only mitigate last week’s issues, but also solve a series of other potential problems with League of Legends core networking architecture. Our teams are already on site in Germany making preparations for a smooth maintenance next week.

As part of the commitment we’ve made to your service this means introducing new core networking hardware to form the backbone of the European Platform, and is the next step in an on-going process of investment into new equipment."
