I'm trying to connect to swift.ca-ns-1.clouda.ca:8443 via SSL. I can connect to this server from multiple other machines including other fresh 16.04.1 boxes (not on GCE), and I connect to it from other GCE instances that are not Ubuntu 16.04.1, but when I try connecting from any Ubuntu 16.04.1 GCE instance the SSL handshake fails. I've posted an example output from openssl below. Note that I can connect to every other SSL server I've tried. CloudA themselves couldn't figure it out. Any ideas?
% openssl s_client -connect swift.ca-ns-1.clouda.ca:8443

UPDATE: I've confirmed this only happens in the us-central1 zones (any subletter is also affected). Creating an instance in us-east1 works perfectly fine.
