Cool, we opened an account with triodos last week too. I always knew SSL allows DOS amplification and so enforce it sparingly and hope "let's encrypt" never make ssl everywhere (apparently it's goal stated by eff) a requirement and that sites don't get penalised for actually being more correct (secure flagged cookies and http forced where it's not needed and https forced where it is). Checking my server it seems my pf.conf isn't quite as useful as I thought due to renegotiation DOS. Do you have to recompile to make libressl use one tcp connection for each ssl connection?

I assumed they already were and will have to work out if it's my knobless csr generation or startssl's cert creation?
