+# Github Actions Metrics
+Information on Github hosted runners like the Azure region they run on is
+necessary info when optimising CD/CI pipelines(especially network latencies and
+route path bandwidth). Github does not disclose it so I did it myself.
+
+Using this info, place the resources(DB, object storage, other instances) near
+the runners are usually run.
+
+A few pieces of info I could gather online:
+
+- Azure doesn't provide a list of VM service endpoints like AWS
+- Github-hosted Actions runners are actually Azure VMs (surprisingly, not in a
+  container)
+- Github is hosted in the data centre somewhere in the US, probably in the same
+  data centre where Azure is present
+
+Microsoft definitely has more points of presence than any other cloud service
+providers, but there's no official list of data center endpoints to ping. If you
+look at the map,
+
+<a href="https://aws.amazon.com/about-aws/global-infrastructure/regions_az/">

+</a>
+<a href="https://datacenters.microsoft.com/globe/explore">

+</a>
+
+they're close enough. For most devs, all that matters is probably how close
+their S3 buckets are to the Github Actions runners. Some AWS and Azure regions
+are under the same roof, but then again, no official data.
