Wizards pictures

I've found that my pictures site " Wizard " and another one I have at MSN have been unavailable for veiwing for a couple of days. Anybody have any ideas on how I could find out from MSN whats going on. I'm hoping its just something temporary. Is something like this not normal from time to time or is there possibly something more sinister afoot? This is the first time I can remember this happening at the two sites. Thanks in advance for any help :-)
