Scheduled maintenance is currently in progress. We will provide updates as necessary.

Scheduled

The Mumbai (GINMU) WSS point of presence (POP) will undergo maintenance beginning on January 28th, 2021 at 12:00 UTC for a duration of up to 36 hours.

  • Expect the site to be completely unavailable during the maintenance window.
  • P address changes will occur so it is imperative to adjust access control lists appropriately.
  • Carefully review the information below to avoid disruption of service.

    Ingress IP Addresses The IP addresses you forward traffic to for filtering. The IP address must match the connection method. For example, do not connect IPsec tunnels to the IP addresses for WSS Agent. IPsec / Proxy-forwarding / Explicit / SEP Agent (Explicit Mode):

  • 148.64.4.164 - NO CHANGE

    WSS Agent / Unified Agent / SEP Agent (Tunnel Mode):

  • 148.64.5.164- NO CHANGE
  • 168.149.169.164 - NO CHANGE
  • 34.93.66.164 - NO CHANGE
  • 34.93.160.164 - NO CHANGE
  • 34.93.226.164 - NO CHANGE

    Egress IP Addresses The IP addresses WSS will use to access content on your behalf and to deliver filtered content to your users. If you use application or firewall access control lists, add new IP ranges prior to the maintenance:

  • 148.64.1.0/24 NEW

  • 168.149.169.0/24 - NO CHANGE
  • 168.149.172.0/24 - NO CHANGE
  • 168.149.173.0/24 - NO CHANGE
  • 148.64.22.0/24 - NO CHANGE

  • 148.64.4.0/24 - NO CHANGE
  • 34.93.66.0/24 - NO CHANGE
  • 34.93.160.0/24 - NO CHANGE
  • 34.93.226.0/24 - NO CHANGE
  • 148.64.5.0/24 - NO CHANGE

    Impact Expect the site to be completely unavailable during the maintenance window.

    Required Action Failure to make these changes could prevent users from connecting to WSS, accessing third party web applications, or authenticating against the service using the Auth Connector (where applicable).

  • Firewall rules regulating connectivity to/from your network to WSS should be adjusted to allow traffic to pass to the IP networks listed above.
  • Third party applications that regulate connections by source IP address should be updated to accept connections from the egress IP networks listed above to ensure traffic proxied through WSS can reach the application.
  • Auth Connector must be able to communicate with all egress ranges listed above on TCP 443, where applicable.

    Guidance for specific connection methods:

  • IPsec: Switch to your secondary tunnel prior to the maintenance window.
  • WSS Agent and Unified Agent: Update firewall rules to allow access to the new ingress IP address prior to the maintenance. User traffic will be automatically redirected by the service to the nearest alternate site during the maintenance window.
  • SEP Agent: User traffic will be automatically redirected by the service to the nearest alternate site during the maintenance window.
  • Explicit proxy and proxy forwarding: Customers directing traffic to proxy.threatpulse.net will be automatically redirected by the service to the nearest alternate site during the maintenance window.

    WARNING: Any customer, regardless of connection method, with a configuration pointing to a specific site or IP address must manually failover to a secondary site during the migration window to avoid an outage. Explicit redirection should never point to an IP address. Only IPsec connections should be directed to IP addresses.
