This is very misleading and dodgy. GCP/GCE regions were (reportedly) affected. Gcloud apis were affected even in EU. "others" is a pretty big word here.
I don't want to take away from anyone that suffered a significant outage, but the impact did seem to depend on which region you were in, and Google explicitly stated as much in their blog post.
There was no 'increased latency' and 'partial' outages. It was completely failed for nearly 4 hours. Google console showed a friendly message that I have not yet setup my first GKE cluster and to click here to try it out. They even offered me a $300 credit for first time use.
