Identified - Dear Valued Customer,
We are currently responding to a critical facilities issue affecting our Phoenix, Arizona data center.
A major chiller equipment failure at the facility has significantly reduced cooling capacity, resulting in elevated temperatures and an increased risk of service disruption and potential hardware impact.
The data center provider is actively working to restore normal cooling operations. Replacement work is underway, with current estimates indicating repairs may take 10–16 hours or longer.
Additional information regarding the facility incident is available on the data center provider's status page:
Our teams are closely monitoring conditions and working directly with the data center provider to minimize customer impact. To protect customer infrastructure and reduce the risk of hardware damage or data loss, we may need to perform controlled shutdowns of affected systems if facility temperatures reach unsafe levels. Where necessary, we will prioritize orderly shutdown procedures to protect the underlying infrastructure.
Customers with services hosted within the affected Phoenix facility should prepare for potential service interruptions while remediation efforts continue.
We understand the seriousness of this situation and the impact an extended disruption may have on your business. We will continue to provide updates as conditions change and additional information becomes available. We sincerely apologize for the disruption and appreciate your patience as we work to protect your infrastructure and restore normal operations.
Sincerely, Nexcess Support Team

Investigating - A security vulnerability, CVE-2026-65640, has been identified in WordPress that could allow an authenticated Author-level or higher user to achieve remote code execution through a malicious file upload on sites using Imagick and Ghostscript.
The vulnerability has been addressed through updates across supported WordPress branches.
Patched Versions:
Customers should update to the following patched version for their respective WordPress branch: 7.0.4 6.9.7 6.8.8 6.7.7 6.6.7 6.5.10 6.4.10 6.3.10 6.2.11 6.1.12 6.0.14 5.9.16 5.8.15 5.7.17 5.6.19 5.5.20 5.4.21 5.3.23 5.2.26 5.1.24 5.0.27 4.9.31 4.8.30 4.7.35
Recommended Action:
Customers are strongly encouraged to update WordPress core to the latest available patched version and ensure automatic updates are enabled where appropriate.
Customers with automatic updates enabled should receive the applicable update automatically. However, we recommend verifying the currently running WordPress version to ensure the security update has been successfully applied.
We will continue to monitor the situation and provide further updates if required.
If you need assistance or have any concerns, please reach us via live chat or via a case.
Investigating - A high-severity reflected XSS vulnerability, CVE-2026-64638, has been identified in the WordPress login interface. Exploitation requires a victim to visit a specially crafted URL and, under specific conditions, could potentially lead to PHP code execution.
Impacted versions
Impacted versions: WordPress 4.7 – 7.0.2 (every release on every branch) WordPress 4.6 and earlier — end of life, no patch available
Fixed versions: WordPress 7.0.3 WordPress 6.9.6 WordPress 6.8.7 Equivalent minor releases on every remaining supported branch back to 4.7
Recommended Action Customers are strongly encouraged to update WordPress core and ensure automatic security updates are enabled where appropriate. Since exploitation requires user interaction, customers should also remain vigilant against phishing attempts and avoid clicking suspicious or unsolicited links. Customers with automatic security updates enabled should receive the applicable update automatically; however, we recommend verifying the currently running WordPress version. There is currently no reported evidence of widespread exploitation in the wild. We will continue to monitor the situation and provide further updates if required.
If you need assistance or have any concerns, please contact our Support team.

Aug 13, 12:30 EDT
In progress -
Scheduled maintenance is currently in progress. We will provide updates as necessary.
Aug 13, 09:30 EDT
Scheduled -
We are performing critical network infrastructure upgrades to significantly improve network stability and reliability. This work involves upgrading the DWDM (Dense Wavelength Division Multiplexing) system capacity from 200G to 400G between our data centers and the ATT network.
This maintenance is scheduled to begin Thursday, August 13, at 9:30 am EDT, and is expected to last for 3 hours.
While we typically strive to perform network maintenance outside of business hours, this one will take place inside business hours, due to the specific availability requirements of our third-party vendors.
To maintain operational continuity during this process, multiple layers of redundancy are in place to support these upgrades. While we do not anticipate any service outages, some users may experience brief latency in rare situations as traffic routes adjust. We appreciate your understanding as we complete these necessary performance enhancements.
