For the majority of the past five years, Pushover has run on one physical OpenBSD server. It does have a hot spare hosted with another company in another part of the country, but usually everything has been served from just one machine at a time. Its MariaDB database is replicated in a master-master configuration over a secure tunnel between the servers so that either node can become active at any time.

When I wanted to take the primary server down for upgrades or the server’s network provider was having routing troubles, I would update DNS for various pushover.net entries to point at the other server’s IPs where all of the components were already running.

On March 7th, 2012, I announced the launch of Pushover, a simple mobile notification service with device clients available for Android and iOS. I kept some notes during the development process, which mostly occurred in the evenings and weekends around my other work.

I had been using Notifo for a year or so to receive push notifications on my phone from my custom network monitor, but last year the free service announced it was shutting down. When I switched back to my Android phone a few months ago, I was unable to download Notifo’s Android app which never made it out of beta.
