Asana unreachable for some users

Final update

Incident: On 2024-07-01 22:30 UTC, changes related to ongoing work towards smaller, independent deployment environments resulted in an invalid configuration affecting approximately 18% of our customers in our US datacenter.

Our metric considers a weighted average of uptime experienced by users at each data center. The number of minutes of downtime sh
