EMEA Issue

Does anyone what actually is wrong with (m)emea servers and/or pcs?

Riot EMEA use the same PCs as they do for league and have not updated the hardware because you can run league on a potato.
PCs start having issues that cause constant tech pauses throughout games.
officials decide that LAN is the problem so they switch to online for the TL vs KC game.
proceed to have 3 hours worth of tech pauses in 1 single map and decide to postpone the rest of the games until they fix the issue.
