Exchange Online Connectivity Issues

Microsoft To Do
Current status While validating the targeted change, we found that many of the affected servers have become unresponsive, which is preventing us from confirming whether the change is effective. We're restarting these servers so they can come back online with the change in place, and we're applying the same approach to additional affected portions of our infrastructure to validate the results more broadly.
Previous Status While we haven't identified any recent changes that correlate with the start of impact, our investigation indicates the failed health checks may originate from a specific component on the affected servers that's responsible for processing them. We're deploying a targeted change to bypass this component on a subset of servers to validate whether this restores availability, and we've taken steps to prevent additional servers from being removed from service while we work to return the affected servers to service. We're also investigating why affected servers are experiencing elevated processor usage while handling requests.
Scope of impact This issue may affect users attempting to access the affected Microsoft 365 services.
IMAP and POP3 mailboxes connected to Outlook are currently affected by the Microsoft outage. As a workaround, please access your email via webmail at webmail.emailsrvr.com (this applies to IMAP/POP3 mailboxes only, not Exchange mailboxes).

PHP Vulnerabilities
Email hosting Engineering team is aware of the recently identified critical PHP vulnerabilities (CVE-2026-109618 and CVE-2026-109619). Engineers are actively monitoring vendor advisories and coordinating the availability of security patches. While vendors have started releasing updates, some packages are still being synchronized with our repositories.
Engineers have identified an API Wiki site that may be susceptible to these CVEs http://api-wiki.apps.rackspace.com/api-wiki/. Pre-emptively and as a precaution to protect customers and systems, this site will be taken offline until further notice. This action should not disrupt Admin Email Hosting functionality and services. The action will only impact access to the API Wiki documentation.
Customers who continue to require access to the API Wiki content are advised to engage the Support team. The documentation remains available and can be delivered through alternative means.
We will continue monitoring developments and provide further updates as appropriate.
