Apparently, one of our datacenters reports is under a DDOS attack which affects availability of Wuala and causes connection problems. We have no estimate when the problem will be resolved.
Update 16:50 CEST:
Connection problems have been partially resolved. You can still experience some higher waiting time than normal in Wuala because of recent events. Datacenters maintainer is working on resolving the issue.
Update 09/07/11 10:30 CEST:
Issue has been resolved.
