[Global] Azure performance issues affecting some of CodeTwo apps

The issue appears to be resolved now. A bunch of guys were about to turn blue (when we realized Microsoft has messed up the DNS configuration) - we're breathing again. Thank you for your patience and understanding!

This was a widespread incident affecting multiple Microsoft resources worldwide. Some of the performance issues we experienced as a result were unavoidable. Nevertheless, we’ll continue to enhance our high availability capabilities to make our are services more resilient to similar problems in the future. Please stay tuned, and thank you for your continued trust and business.

If you have any questions or need assistance, please reach out to our Customer Success Team - we’re online 24 hours a day. And yes, our SOC Team also works around the clock, continuously monitoring our services both reactively and proactively. These teams, along with our Product Team, will remain on “DEFCON 1” until we’re certain the issue has been fully mitigated.

We’re seeing signs of recovery as Microsoft continues working to resolve the DNS configuration issue on their end. Some users are no longer experiencing problems accessing CodeTwo resources, while others may still encounter delays or temporary unavailability when accessing CodeTwo apps.

According to Microsoft, the full recovery process on their side may take up to four hours - they are planning to finish by 23:20 UTC on 29 October 2025.

Microsoft is currently working to revert changes caused by a faulty DNS configuration, which has led to widespread service disruptions. In response, we have proactively rerouted some of our services away from the affected nodes, successfully bypassing the impacted Azure Front Door infrastructure.

At this time, users should be able to access the Signature Management App, although for some, it may take up to 45 minutes for changes to propagate. However, the Admin Panel may still be temporarily unavailable.

Our telemetry confirms that email signature imprinting services have remained operational throughout the Microsoft Azure outage and have not been affected.

Here's another update from MICROSOFT suggesting it is a DNS issue (again):

Starting at approximately 16:00 UTC, we began experiencing DNS issues resulting in availability degradation of some services. We have taken action that is expected to address the portal access issues here shortly. We are actively investigating the underlying issue and additional mitigation actions.

Here is the current status from Microsoft:

User impact:
Users may be unable to access the Microsoft 365 admin center and see delays when accessing other Microsoft 365 services.

More info:
Additionally, admins are reporting issues when attempting to access some Microsoft Purview and Microsoft Intune functions. Users are also seeing issues with add-ins and network connectivity in Outlook.
Current status: We're reviewing reports of an issue impacting Microsoft Azure and Microsoft 365 services, including impact to the Microsoft 365 admin center and other services, including but not limited to those described in the more info section of this communication. We're reviewing corresponding service telemetry to isolate the cause of the issue and determine our next troubleshooting steps.

Scope of impact:
Any users attempting to access Microsoft 365 services may be impacted.

Downdetector is currently reporting widespread performance issues affecting Azure and Microsoft 365 applications globally. We are also observing partial impact on Amazon Web Services at the same time.

We are actively monitoring CodeTwo mail flow and can confirm that email signatures are still being added as expected. We are currently awaiting an official statement from Microsoft regarding the ongoing service disruptions.

We are currently observing degraded performance across Azure resources globally. This appears similar to the issues experienced with Azure Front Door a couple of weeks ago caused by Microsoft engineers.

As a result, some users may encounter difficulties accessing Microsoft 365 services and certain CodeTwo applications that rely on the same infrastructure. Affected services may include the CodeTwo Admin Panel and Signature Management Apps, which are used for managing rules, signatures, and additional configuration settings.

Our telemetry indicates that mail flow remains uninterrupted at this time, and email signatures are being applied as expected.
