Opinion based on stated facts.

Please share the information you have which contradicts the conclusions I have drawn from Github's statement.

(And we know they're liars. They report very few of the actual incidents they have; see for example https://mrshu.github.io/github-statuses/)

I don’t owe you anything, much less a separately sourced counterargument. You openly admit that your opinion is not based not on GitHub’s proffered statements but on your self-admitted assumption that GitHub is actively lying in an attempt to cover up an Azure-related root cause.
