August 08, 2022

Connectivity Tests now includes a feature that performs live data plane analysis by testing connectivity between a VM and a Google network edge location. This feature is available for the following traffic flows:

  • Between VM and non-Google Cloud network
  • Between VM and Cloud SQL instances

In the Google Cloud console, you can see the results of this analysis in the column labeled Last live data plane analysis result. In the gcloud command-line and API responses, you can see the results in the probingDetails object.

August 05, 2022

You can now schedule a custom cycle to refresh shadowed rule insights in Firewall Insights. For more information, see Schedule a custom refresh cycle.

Firewall Insights now identifies firewall misconfigurations for firewall rules which contain IPv6 IP address ranges. For more information, see Firewall Insights overview.

May 11, 2022

Network Analyzer is now available in Preview.

April 28, 2022

Connectivity to router appliances is now generally available in Network Topology. Google Cloud users can use Network Topology to audit their networking configuration and troubleshoot issues related to the router appliance instances.

April 19, 2022

You can set the observation period for overly permissive rule insights for a period of up to 12 months. For more information, see Configuring observation periods.

January 20, 2022

Overly permissive rule insights are now generally available. For information about these insights, see the Firewall Insights overview.

December 06, 2021

It is now possible to export Firewall Insights data in CSV format. For details, see Exporting insights.

October 28, 2021

Connectivity Tests now supports private IP addresses outside of the RFC 1918 address space. For more information, see Connectivity Tests overview.

September 20, 2021

Connectivity to Cloud VPN and Cloud Interconnect is now generally available in Network Topology. Google Cloud users can use Network Topology to audit their networking configuration and troubleshoot issues related to the hybrid connectivity to and from their on-premises networks.

September 09, 2021

Firewall Insights now provides comprehensive analysis of whether your firewall rules are overly permissive. Through overly permissive rule insights, which are now in public preview, Firewall Insights identifies rules and attributes that could be made more strict and secure.

Overly permissive rule insights include the following:

  • Allow rules with no hits
  • Allow rules with unused attributes
  • Allow rules with overly permissive IP address or port ranges

Firewall Insights uses Firewall Rules Logging to identify these rules. It uses machine learning to predict future usage of overly permissive rules.

By default, the product analyzes the past six weeks when it identifies overly permissive rules. However, you can choose a different observation period.

For more information about overly permissive rule insights, see the Firewall Insights overview. For details about how to enable overly permissive rules, see Using Firewall Insights.

July 23, 2021

Connectivity Tests now includes a feature that verifies connectivity to and from Google-managed services, such as Google Kubernetes Engine (GKE) control planes or Cloud SQL instances. The Connectivity Tests configuration analysis can now run a test and provide an overall reachability result for Google-managed services. For more information, see Connectivity Tests overview.

July 16, 2021

In the Google Cloud console, the trace panel for each Connectivity Test now includes links to VMs, firewall rules, and other resources that were analyzed as part of the test. Additionally, when you view the Result details panel, it now shows the source and destination IP address, the port that was used, and other information about the test. To see screenshots of the enhanced UI, visit Common Use Cases.

July 02, 2021

Connectivity to Google-managed services is now generally available in Network Topology. Google Cloud users can use Network Topology to audit their networking configuration and troubleshoot networking issues related to the different Google services in use.

June 17, 2021

The Connectivity Tests dynamic verification feature is now generally available. This feature uses active probing to verify connectivity between VMs. For more information, see How Connectivity Tests analyzes the live data plane.

June 14, 2021

Google Cloud performance view is generally available in Performance Dashboard.

April 06, 2021

Connectivity Tests now evaluates hierarchical firewall policy rules as part of its configuration analysis. For more information, see Connectivity Tests overview.

March 11, 2021

Connectivity Tests now includes a feature that verifies connectivity by sending probes. This feature, which is in Preview, is available for VM-to-VM tests. In the Google Cloud console, you can see the results of this analysis in the column labeled Last packet transmission result. In the gcloud command-line and API responses, you can see the results in the probingDetails object. This feature complements the existing configuration analysis feature, which evaluates reachability by assessing your network's configuration.

January 15, 2021

The Network Topology graph now includes a checkbox, Show connections for child nodes only on focus, to display only the traffic paths between top-level entities, such as regions. When this checkbox is selected, you can still view the traffic paths between lower-level entities by selecting or holding the pointer over the lower-level entities.
