How we measured a year of availability, the outages in order, what caused them, and what 97% uptime actually means for you.
We checked both .onion mirrors once a day for twelve straight months. Simple ping, recorded time. The result is roughly 97% availability — solid, but the remaining three percent still stings.
Three noticeable breaks occurred during the year, none longer than fourteen hours: two in spring, one in late fall. All traced to infrastructure — a failed mirror sync and a minor server migration. No hack, no vendor drama. PGP channels stayed open, so orders kept moving even while pages flickered.
