I thought that was just me ... I wonder if this is temporary (it has been going for some time) or a more permanent thing, to discourage users to hotlink their stats and pictures .
I've noticed over the last few days that Alexa has been really sluggish. In fact for many hours we couldn't even bring up their homepage. Updating of thumbnails is definitely taking longer 48 hours Cheers, Dave
I had been using Alexa for many years and I do observe that it is fairly slow the past one month possibly because of heavy traffic. It was no longer able to provide info on its traffic.
Alexa was down for me a few days ago and the thumbnails weren't showing, till yesterday they started to show. And yes they are pretty slow for me too.
