We want to make our customers aware of a recently reported security issue concerning the sudo command. To address this problem, AMIMOTO Managed Hosting will be performing maintenance from Thursday, January 28 to Friday, January 29, between 10:00 – 18:00 (UTC). All EC2 instances hosted on AMIMOTO Managed Hosting will be affected, while customers using the Personal Micro or Personal Small plans, which do not support auto-scaling, may experience brief interruptions. All backend work will be done automatically, without any prior or follow-up notifications.
For more information about this issue, please refer to the original announcement from AWS here: https://aws.amazon.com/jp/security/security-bulletins/AWS-2021-001/. If you have any questions or concerns, please do not hesitate to contact our support team. Thank you for choosing AMIMOTO Managed Hosting for your hosting needs.
