Yes, for some reason, my home DNS server resolve it to the wrong IP.
Apparently I’m not the only one been affected though, maybe piclens are changing their IP address, and the old address were cached?

Right now, I have the issue taken care of by disable PicLens:
Go to wp-admin page, on left panel, choose Gallery, then click on Options, uncheck “Activate PicLens/CoolIris support”
