Why is the Main Page sometimes blank?
This has been the case on Friday 5:00 am - 6:50 am PDT and on Saturday 6:20 am - 8:30 am PDT. Then at 8:36 am PDT it is back in full! (But right now the Sweden page is blank instead!)
The server has also been unavailable for some periods. Is there a natural explanation to this, or does it need to be investigated?
