Interesting. Ran this over a few days of logs:
5288 TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384
4633 TLSv1.2 with cipher DHE-RSA-AES256-GCM-SHA384
2343 TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256
1527 TLSv1 with cipher ECDHE-RSA-AES128-SHA
1250 TLSv1.2 with cipher AECDH-AES256-SHA
Everything else is under 500, and the next 2 are the top 2 TLSv1.2 without GCM.
That's a pretty good situation to be in. :)
I've been trying to reach out to the RC4-MD5 users who are unfortunately
still in the top 10 of one of the mail systems I manage.
