It had uptime issues before Microsoft. They just got better at tracking and reporting after Microsoft.

So, before October, they were lousy at tracking downtime issues for 2 years (no downtime from 2016 to 2018), but in November, Microsoft came and gave them the technology to correctly track downtime, and they had their first downtime logged in November.

Is this your argument?

My subjective experience was that it got a lot worse post-Microsoft. I could be misremembering though!
