These service status pages have so many other problems, I can't really get excited about this article's point. As a user of a service, I don't really care that an additional 0.09% of uptime is any more or less difficult to achieve than an additional 0.9%, even if you describe it in terms of fractions of time. I only care about two things: what the service status is right now and your service reliability's impact to me over the long term (get out of here with your 30-day crap).

In the electric utility world we have a few IEEE standardized metrics (with appropriately IEEE'd acronyms) for tracking service reliability that I like much better and always wish for when I'm looking at a status page. Pie in the sky stuff for sure, nobody wants to do this analysis and publish the results without a regulator telling them have to, but c'est la vie.

SAIDI - System Average Interruption Duration Index. How many minutes an average customer experienced service interruption in a year. This is the big one I'd want to see on your service status page IMHO. For the power grid, we consider any outage longer than five minutes to be an interruption ("non-momentary outage").

SAIFI - System Average Interruption Frequency Index. How many total periods of interruption occurred for the average customer in a year.

CAIDI - Customer Average Interruption Duration Index. How long it takes service to be restored for the average customer when there is an interruption.

For the US, here is what these numbers look like: https://www.eia.gov/electricity/annual/html/epa_11_03.html. If you're outside the US look up yours and have a good laugh at us. :)

For the "right now" aspect you have probably visited your utility's outage map, but here I would say we do much better than most utilities. The level of detail on the investigation and resolution is often more detailed, and we usually know better than to bother providing much in the way of a concrete estimate for restoration time of a current outage (though this is getting better in the utility space).

Can we stop with the uptime percentages?
