I made initial version some 12 years ago.

The goal was to have easier discussions about SLA uptime requirements during negotiations for a client of mine. I also wanted an ability to make easy links to calculations when commenting on documents (under different domain initially).

The current stack is rather boring: OpenBSD, httpd, slowcgi and newLISP. httpd replaced Apache some years ago.

I kept adding small features here and there, most recently adding an ability to encode monitoring duration for complex and reverse calculations in the URL as a sequence of 7 letters (a=0, b=1 etc) to make URLs shorter and nicer.

Public API powered by Cloudflare Workers will be announced soon-ish. It wont’t use newLISP, but will be my very first JavaScript program.

EDIT: add info about the technical stack.
