My first employer after I graduated from University had "two nines" (99.x%) of uptime in an industry that claimed to have "five nines" (99.999% 5.26 minutes of downtime a year) as the standard goal in the telcom world. I only worked for that company from 1999 to 2001, but I and others dragged them to "three nines" (99.9x% 8.77 hours of downtime in a year 43.83 minutes a month of maximum allowable downtime) of uptime before I had left.
Circa 2009 with the help of Jävla Fan (nprofile…djn0) outstanding networking skillz, the employer I worked for was up and still passing packets even when AT&T's fiber ring had been cut in several places in the SF Bay Area before a looming strike (e.g. https://www.nytimes.com/2009/04/10/us/10brfs-VANDALSCUTPH_BRF.html).
Last I checked, Amazon/AWS and Alphabet Inc./Google/GCP, Micro$oft/Azure didn't even maintain two nines of uptime. It's definitely astounding to me, how some of the "big" names don't even seem to maintain standards that used to be a given in our industry decades ago. But 100% uptime? Probably not impossible but highly improbable.
