      ouch.. "OCSP checks timeout ~15% of the time, and take 350ms when successful": http://mzl.la/1P8aGs4  - tip: configure OCSP stapling!

      @igrigorik Sadly, nginx and apache's implementations are bad enough that doing so will create even more issues :(

      @selecadm Turned it off. We had weird network timeouts roughly coinciding with OCSP response renewal. I suspect Apache.

      @selecadm @igrigorik Yes. Apache is notoriously bad here. Really, need an ocsp-daemon (which is how IIS does it, and Apple quasi-does-it)

      @selecadm @igrigorik Renew responses at expiry / 2, maintain fresh responses, handle interaction w/ proxy/firewalls as appropriate.

      Replying to @igrigorik

      @igrigorik @ericlaw Unless things changed in past 2mo, it still _blocks_ on startup for response, doesn't renew, and will serve junk data

      @sleevi_ @igrigorik @ericlaw It's not that bad. nginx has always renewed, and has never blocked

          @__agwa @igrigorik @ericlaw It doesn't background renew though - it just evicts current so it stops serving until it renews, right?

          @sleevi_ @igrigorik @ericlaw It kind of does background renew, but only if a worker process is actively receiving new connections.

          @sleevi_ @igrigorik @ericlaw So sometimes it could stop serving OCSP response, but other times renew will be seamless. Yay, nondeterminism!

          @sleevi_ @igrigorik @ericlaw OTOH, not blocking leads to different problem: it will return no OCSP response at all if it's not ready yet
