To clarify something: this outage doesn’t appear to be global, but it is hitting us particularly hard in parts of the US. So for the folks with working VMs in Mumbai, you’re not crazy. But for everyone with sadness in us-central1, the team is on it.
It seems global to me. This is really strange compared to AWS. I don't remember an outage there (other than s3) impacting instances or networking globally.
I’m from the US and in Australia right now. Both me and my friends in the US are experiencing outages across google properties and Snapchat, so it’s pretty global.
