Is Nexcess Server Down?

Our Engineering team has pushed out a security update to distrust the compromised eMudhra intermediate Certificate Authorities. Outgoing secure connections (HTTPS/TLS) to any external service or endpoint relying on the revoked eMudhra intermediate certificates will be rejected automatically. If your integration relies on certificates issued by the affected eMudhra intermediates, ensure your certificates have been reissued under an unaffected, trusted Certificate Authority to prevent connection failures. --- [2026-10-27T11:39:08.963-04:00] (investigating) We are aware of a recently reported security issue involving compromised eMudhra Certificate Authority (CA) certificates that may be present in certificate trust stores across some environments. At this time, we have not identified any service interruptions or confirmed customer impact related to this issue. Our Security and Engineering teams are actively evaluating the situation and working to determine and implement the appropriate mitigation across affected environments. Additional information regarding this issue is available from Sansec: https://sansec.io/guides/compromised-certificate-authority We will provide additional updates as more information becomes available and as our remediation efforts progress. If you have any questions or concerns, please don't hesitate to contact us via live chat or by opening a support case.

During scheduled evening maintenance, our operations team began deploying security patches to update server kernels to address the CVE-2026-74580 (vghost kernel vulnerability). Following the application of the patch and server reboots we identified a subset of our parent servers did not come up cleanly. Our engineering and development teams are actively addressing the down server and are working to bring them back online. Restoring affected parent servers and stabilizing services is currently our highest priority. We sincerely apologize for the unexpected interruption. Our team is working to bring all impacted systems back online as quickly and safely as possible. Further updates will be posted here as soon as new information becomes available.
