I sympathized with them when they said this a handful of months ago, but then I saw this [0] page that shows how it's been shot for years prior (which tracks with my memory).
I feel for the GH engineers that have to deal with this, especially the SREs. I also don't hate the downtime right now, as I'll make a cup of coffee and do something else. I will say though, I did have a hotfix a week or so ago during the Actions outage, which really was a pain.
You're right that getting angry and ranting isn't the right reaction here, but I do no give them the LLM load excuse. I don't give them an out for having awful uptime during work hours for a product we pay quite a bit for as an org.
