How much is Google Cloud Latency (GCP) between Regions?

Invicti Web Application Security Scanner – the only solution that delivers automatic verification of vulnerabilities with Proof-Based Scanning™.

Lately, I started working on a hobby project (Geekflare Tools) to test website performance, taking a screenshot, security check from multiple locations.

Having server requirements in multiple locations means I have to consider the internal latency as a server will talk to each other to deliver the requested content from the requested location.

Google Cloud Platform (GCP) is known for its low latency, and I am happy with Geekflare performance which is hosted on GCP.

You can check the latency to GCP over the Internet by using online latency tools such as Cloud Harmony.

However, I couldn’t find any resource which gives an indication of latency between Google Cloud regions.

So I thought to do a little test myself and here is the result.

Google Cloud data centers are available in the following twenty-four regions.

  • Iowa, US Central
  • Oregon, US West
  • North Virginia, US East
  • South Carolina, US East
  • Belgium, Europe
  • London, Europe
  • Frankfurt, Germany
  • Singapore, South East Asia
  • Taiwan, East Asia
  • Tokyo, North Asia
  • Sydney, Australia
  • Sao Paulo, Brazil
  • Mumbai, India
  • Montreal, Canada
  • Netherlands, Europe
  • Los Angeles, US West
  • Salt Lake City, US West
  • Las Vegas, US West
  • Zürich, Europe West
  • Jakarta, Asia Southeast
  • Finland, Europe North
  • Hong Kong, Asia East
  • Osaka, Asia Northeast
  • Seoul, Asia Northeast

I provisioned an f1-micro instance in all the regions with Ubuntu 20 LTS. I didn’t install any additional software and did a ping to another region server 10 times over private IP.


And here you go with the average latency results in milliseconds.

  • Green = Less than 100 ms
  • Orange = Between 100 to 200 ms
  • Red = Above 300 ms


  • Sydney & Singapore got high latency from/to all the regions.
  • Oregon perform better to connect to Asia
  • Tokyo got the lowest latency to connect to Asia and the US
  • London play better in Europe

Above should give you an idea of where to host your services internally for better results.
