Http2 deployed for many collections

If your collection is accessed via a URL that starts with https, and your collection is either under the www.ibiblio.org namespace or a domain that points to vhost.ibiblio.org, as of a few minutes ago most clients (both recent Firefox and Chrome) will prefer http2 vs. the older http/1.1 when connecting. For the vast majority of users, this will be a big improvement. If for some reason you think the change has caused a problem for your collection, please let us know. If you’re curious to read more background, here’s a link on http2.
