I started a scan of Alexa's top 1 million websites. It's going to
take a few days to have all the results.
So far, 21 out of 1396 websites scanned support neither AES or 3DES.
I'm about half way through the scan, but it's unlikely that the numbers will
change from now. The raw results are below, and I posted an analysis on my
blog: https://jve.linuxwall.info/blog/index.php?post/TLS_Survey
