When you order a Dedicated Interconnect connection, you must specify a colocation facility where your network meets Google's network. In most cases, select a facility that's geographically close to your on-premises network.
To view a list of these facilities in the documentation, see All colocation facilities .
To use the Google Cloud console or Google Cloud CLI to view a list of facilities, see the following steps.
