lol...yeah we have that established within the team now. But still a challenge to find out a right contact across teams at 3am in the morning if the issue is from another team. May be we should build a service level ownership list so that we can tag them (in addition to their on-call). Curious to know what level of ownership you were referring about?

Basically the same as yours: who to call when shtf. The tricky part is that managers don't do trench work so once the developer responsible does not reply then the oncall has to figure it out.

Got it. I wish there was an up to date service level owner identified which will then reduce this to just a lookup and tagging. I have seen few engineering teams in other companies started doing that.
