Colocation Facility Locations with Low Latency

If your Google Cloud Platform workloads over Cloud Interconnect – Dedicated require 5 milliseconds of round-trip latency between VM instances in the specified region and its associated interconnect locations, refer to the Locations table in this document.

The pricing for low-latency locations is the same as for all other locations.

If your workloads don't require low-latency connectivity, you can use any of our Colocation facilities locations.

Requirements and recommendations

For Google Cloud Interconnect - Dedicated your network must physically meet Google's network in a supported colocation facility, also known as an interconnect location), where a vendor, the colocation facility provider, provisions a circuit between your network and a Google Edge Point of Presence. For more information, see the Cloud Interconnect Overview.

The Region served as listed in the table below indicates the regions in which you can create VLAN attachments, which affects latency and egress costs. For example, if you have VM instances in region us-east4 (Virginia), you might create a dedicated connection in Ashburn and then create an interconnect attachment (VLAN) in us-east4. That way, your traffic doesn't have to travel far to move between your VM instances and the dedicated connection, resulting in lower latency than, for example, creating a dedicated connection and an interconnect attachment in Europe.

Also, it's more cost effective to create interconnect attachments in the same regions as your VM instances because you don't have to pay inter-region egress costs when VM instances send traffic to your on-premises network.

Other GCP location options

  • Network edge locations allow you to peer with GCP and connect to GCP services. Peering does not require Cloud Interconnect.
  • Cloud CDN locations use Google's globally distributed edge points of presence to cache HTTP(S) load balanced content close to your users. Caching content at the edges of Google's network provides faster delivery of content to your users while reducing serving costs.

Locations table

The following table lists low-latency locations where you can create dedicated connections. The locations are organized by the GCP regions served, metropolitan area, and then by metropolitan availability zone. The name of each location indicates its metropolitan availability zone, such as the zone1 in iad-zone1-1.

You can also use the console or gcloud command-line tool to list locations.
