[Identified] We understand that security updates and news of breaches may cause concern, and we want to reassure you of Silversky's commitment to your security. Following the recent news of a breach at F5, we would like to provide you with a clear update on our response and the impact on our services. **Services Affected** Silversky utilizes F5 Big-IP load balancers—which help distribute network traffic to ensure stability and reliability—solely as part of our Hosted Exchange product line.

All other Silversky services remain fully secure and unaffected. **Actions Taken** To address this situation, Silversky is: - Implementing all recommended security changes proposed by F5, including timely patching. - Conducting enhanced security monitoring of our Hosted Exchange environment. - Continuing to assess and apply additional hardening measures to mitigate any identified vulnerabilities. We will continue to monitor the situation closely and will provide further updates as necessary to keep you informed. In summary, Hosted Exchange is the only Silversky service affected, and all recommended security measures are in place. We are committed to keeping your data safe and maintaining your trust.

Important Advisory: Direct Send Risks in Microsoft 365Operational

[Monitoring] Client Contacts, Subject: Important Advisory: Direct Send Risks in Microsoft 365 SilverSky is issuing this advisory to inform you of an increased threat activity targeting Microsoft 365 Direct Send configurations. Recent attack patterns indicate that adversaries are exploiting this mail relay method to bypass traditional controls and deliver malicious content. Why This Matters Direct Send is commonly used for: - Multi-Function Printers (MFPs) and scanners - Line-of-Business (LoB) applications - Vertical integrations requiring SMTP relay While disabling Direct Send may seem like a quick fix, doing so without proper planning can disrupt critical workflows and compromise message hygiene and DMARC alignment. For these reasons, Microsoft and SilverSky recommend a measured approach rather than immediate deactivation. What We’re Seeing SilverSky’s Email Protection Suite (EPS) provides a strong security layer, but admins should remain vigilant for: - Unusual relay patterns from non-standard IPs - Spoofed internal domains and users - High-volume bursts from devices or apps that normally send low traffic Our Position SilverSky aligns with Microsoft’s guidance: - Do not disable Direct Send without a validated alternative. - Implement strict connector scoping and authentication controls. What You Should Do - Review your SMTP relay configurations for anomalies. - Validate that connectors are scoped to known and authenticated systems. - ‎SilverSky has options if you currently leverage Direct Send and need additional assurances. Our Ironscales product can be deployed instead of disabling Direct Send. - If you suspect compromise or need assistance, contact SilverSky to schedule a complimentary consult. SilverSky is committed to helping you maintain secure and compliant mail flows. If you have questions or require support, please reach out to your Modern Work Concierge or open a ticket with our Service Desk. Thank you for your attention to this matter.

[Resolved] Microsoft Azure Connectivity issues are resolved. Closing out this incident Thank you, SilverSky Support

[Monitoring] Microsoft Azure Update as of 19:22 UTC on 29 October 2025 Critical Azure Front Door - Connectivity issues - Observing recovery Starting at approximately 16:00 UTC on 29 October, 2025, customers and Microsoft services leveraging Azure Front Door (AFD) may have experienced latencies, timeouts, and errors. We have confirmed that an inadvertent configuration change was the trigger event for this issue. Current status: We initiated the deployment of our ‘last known good’ configuration, which has now successfully been completed. Customers may have begun to see initial signs of recovery. We are currently recovering nodes and routing traffic through healthy nodes, and as we make progress in this workstream, customers will continue to see improvement. Customer configuration changes will remain temporarily blocked while we continue mitigation efforts. We will notify customers once this block has been lifted. Some customers may also have experienced issues accessing the Azure management portal. We have failed the portal away from AFD to mitigate these access issues. Customers should now be able to access the Azure portal directly, and while most portal extensions are functioning as expected, a small number of endpoints (e.g., Marketplace) may still experience intermittent loading problems. At this stage, we anticipate full mitigation within the next four hours as we continue to recover nodes. This means we expect recovery to happen by 23:20 UTC on 29 October 2025. We will provide another update on our progress within two hours, or sooner if warranted. Although we are seeing signs of recovery and have an estimated timeline, customers may also consider implementing failover strategies using Azure Traffic Manager to redirect traffic from Azure Front Door to their origin servers as an interim measure. Thank you, SilverSky Support

[Monitoring] Microsoft Azure Update at 17:51 UTC on 29 October 2025 Azure Front Door - Connectivity issues Starting at approximately 16:00 UTC, customers and Microsoft services that leverage Azure Front Door (AFD) may have experienced issues resulting in latencies, timeouts and errors. We have confirmed that an inadvertent configuration change as the trigger event for this issue. We are taking several concurrent actions: Firstly, where we are blocking all changes to the AFD services, this includes customer configuration changes as well. At the same time, we are rolling back our AFD configuration to our last known good state. As we rollback we want to ensure that the problematic configuration doesn't re-initiate upon recovery. Customers may have experienced problems accessing the Azure management portal. We have failed the portal away from AFD to mitigate the portal access issues. Customers should be able to access the Azure management portal directly, while all portal extensions are working correctly there may be a small number of endpoints that might have a problem loading (i.e. Marketplace). We do not have an ETA for when the rollback will be completed, but we will update this communication within 30 minutes or when we have an update. While we don't have an ETA yet. customers can consider implementing failover strategies with Azure Traffic Manager, to fail over from Azure Front Door to your origins: https://learn.microsoft.com/azure/architecture/guide/networking/global-web-applications/overview For SilverSky customers, this is impacting: SilverSky Phone Support Administrative Management of Customer O365 Tenant including any M/A/C functionality Thank you, SilverSky Support

October 29, 2025 5:12PM UTC
[Monitoring] This is a Microsoft Notification: Azure Portal Access Issues Starting at approximately 16:00 UTC, we began experiencing Azure Front Door issues resulting in a loss of availability of some services. In addition. customers may experience issues accessing the Azure Portal. Customers can attempt to use programmatic methods (PowerShell, CLI, etc.) to access/utilize resources if they are unable to access the portal directly. We have failed the portal away from Azure Front Door (AFD) to attempt to mitigate the portal access issues and are continuing to assess the situation. We are actively assessing failover options of internal services from our AFD infrastructure. Our investigation into the contributing factors and additional recovery workstreams continues. More information will be provided within 60 minutes or sooner. This message was last updated at 16:57 UTC on 29 October 2025 This is impacting: SilverSky Phone Support Administrative Management of Customer O365 Tenant including any M/A/C functionality We will update this as we receive additional information from Microsoft.
