October 2019 update

certbot cert expired on amazon2 instance.

I could not for the life of me get the new cerbot client to work on amazon 2 . A bit of googling showed me that I was not alone and that others are having similar problems. so in a classic IAC style , I _just_ swapped my OS to ubuntu 18 and it worked.

note that there are some thing s that still needs work , for example i just learn that google PageSpeed service is no longer, the software ( apache module ) still exists.

and I need to install it https://www.modpagespeed.com/doc/download
