SLAs
99.5% 1 day 20 hrs downtime a year
99.9% 8.5 hrs downtime a year
99.995% 26 minutes downtime a year

And another point to remember is that if your crappy company website built on SharePoint 2010 is only ever visited by the companies monitoring servers, spiders and script kiddies and no one would notice it was down if you disabled the monitoring, uptime may be 100% but no one cares Aaron.
And if you patched the damn servers and it wouldn't be 100% Aaron. It's not rock solid hosting its just a shite website Aaron. No one visits the website because the OS and SharePoint are more recent than the content Aaron.

You missed out that Teams is also now showing 9 video feeds in meetings; at least on some tenancies/devices - my work laptop connected to a 23" ext. monitor started showing 9 yesterday, but my personal laptop (12" screen I think) using a charity's tenancy was still showing just 4 last night (although it may not have had chance to update).
