In the past two weeks, we've held two Availability Review meetings featuring excellent presenters. These meetings facilitated fruitful discussions on how we can reflect and learn from customer incidents. (In case you missed any, you can find the recording for 08-27 and 09-04)🤗

To enhance the efficiency of our AR meetings, here's a guide on the current Availability Review process and how AR issues should be completed. We're also integrating GHES-specific requirements into overall GitHub automations. Future improvements are expected to ease and eliminate more manual steps.😌

🐾 Process at a glance:

#	Step	Info
1	Availability Review created at end of GHES SEV 1	this will be automated in future

We would like to have runbook to facilitate engineer oncall

review existing runbook from support which are related to GHES engineering.

A spreadsheet is created now to start with the runbooks that are over 1 year old

create runbooks for GHES engineering with catagorized topics

Since this is the 3rd time a ticket is created because of this check added a while back, I think it is a good idea to have a summary and clarification on what will be allowed as a noproxy
