Here's something to watch. In providing a security certificate (SSL) to enable https everywhere for your site, your host may have to propagate a new IP address (especially if its not a free one).
There are many products to track propagation. Generally the certificate will not work until all telecom companies around the world have changed the A record IP. The http sometimes will not work either if there is CDS,
This means that after the "net neutrality repeal" rules take place on April 23, there is at least a theoretical possibility that a domestic (US) telecom could reject a site if it has announced it will do so in advance for some kinds of sites. This is something to watch for.
