For 2017 calendar year.

good: ~99.50% major: ~0.04% minor: ~0.46%

There's 7 years of history on their status API. https://status.github.com/api/daily-summary.json

That would be 18 days out of a year. I'd be amazed if it was that low. I'd expect closer to 98-99% (7-3 days per year)

95% would mean it would have over 18 days offline!

I wouldn't even put it in the 99% (3.7 days) uptime category either.

Not really.

It is just very public when they go out.

Steam, Blizzard, Activation are down at least 6 hours a week. While Bank of America is offline 24hours/month. Scheduled downtime is still downtime.

> Scheduled downtime is still downtime.

Except in the SLA.

I've argued more than once when watching a vendor announce "emergency scheduled maintenance"(!) as an outage is looming.

The stat you refer to is for the day only. Status page shows 99.5159% for the past month, I'd guess it would be in that range for the year aswell.

no

It may feel that way when the outages are during your business hours.
