Wordfeud, server maintenance & monetization

wordfeudSo I’m a Wordfeud-addict (you know, Scrabble without the TM infringement) and the game is down since this morning. Their Twitter-account reads;

#Wordfeud servers are going down for maintenance around 06:00 CET. We expect 2-3 hours of downtime.

This message is 9h old but still no Wordfeud, so they must be facing major problems. Which begs the question; is Bertheussen IT into server-technology? And wouldn’t they invest more if paying customers could simply stop paying if service-level became too bad instead of paying a one-time fee?
