Outages at CircleCI have been common since the service has been launched.

Amazon is about to lay off 18k people. Circle isn't in a unique position to my understanding. Did CircleCI lay off some group or set of really important and key personnel?

Software supply chain attacks affect everyone. Is there some way that Circle is more vulnerable to this type of attack?

I would imagine GitHub Actions and always maturing CI tooling baked into cloud providers are rapidly eroding the market share of dedicated services like CircleCI.
