Recently I discovered that many of the services I deployed upon my nomad cluster didn't had the SSL A grading I expected them to have. Somehow I asumed the traefik letsencrypt implementation got the A rating by default.

After running the testssl.sh container it turns out they don't;

$ docker run --rm -ti drwetter/testssl.sh domain.org
