T2FINLAND now has a new cert, and T2HAM & T2USANW will have their new 
certs installed soon.

We have nagios alerts for these servers already, we'll need to configure 
the SSL test which triggers a warning email a month or two before actual 
expiration. Nagios has such a test program available, it just needs to be 
configured, to avoid silly newbie accidents like this. :)

As for letsencrypt.org, I'm aware of it and a good number of T2 folks are 
using it for other purposes.

The T2 SSL certs are issued by a CA of our own, which allows us to embed 
the server ID ("callsign") in the certificate subject in the same format 
as LoTW client certificates have them, and also embed the rotate hostnames 
in the alternative name field. These would not be available with 
letsencrypt.org. We can also automate certificate issuing and renewing 
with a bit of scripting from the sysop portal, reducing manual work from 

         Subject:, CN=amsterdam.aprs2.net

             X509v3 Subject Alternative Name:
                 DNS:rotate.aprs2.net, DNS:euro.aprs2.net
