This incident is related to a recently identified security vulnerability in cPanel & WHM login. cPanel would release a new security patch tonight to fix all the identified vulnerabilities and we have planned to install the same on all our servers as soon as released. Given the nature of this vulnerability, and our immediate priority is to secure data and prevent any impact, we are blocking certain access (WHM/cPanel/Webmail) temporarily, until further notice. Your email functionality continues to work (IMAP/POP), we request to use email clients to access your emails in the meantime. We will keep this post updated once we install the patch on respective servers. Thank you for your understanding and support.

The temporary restrictions on WHM, cPanel, and Webmail access have now been removed, and services should be accessible normally. Our senior system admins continue to install new security patch, and monitor the servers in background. As an additional precaution, SSH and SFTP access (ports 22/2222) remains temporarily restricted while further security validation and patching activities continue. Workaround for VPS & Dedicated customers: Access the server terminal via WHM >> Terminal: These steps are being taken proactively to help safeguard customer environments while additional security updates are reviewed and applied. Thank you for your patience and understanding.
