Fetch CloudWatch metrics from other regions

Hey there !
I'm a bit confused by what the github repo states :
Choose the AWS region different from your service's region. If both your service and its status page rely on the same region, the region outage may stop both.
I'm not sure how I can achieve that as, when I try to add a metric, I don't have access to the metrics coming from a different region. Am I missing something?

Oops, that’s a bug. Only the metrics from the LambStatus' region are fetched. The metrics from other regions should be fetched, too. I will fix this on the weekend and release the new version.
