How to Prepare Your Website for Data Center Outages: Business Resilience Checklist
Following strikes on Yandex data centers, many businesses discovered that their sites and all backups were stored in a single location, leading to complete outages. The article provides a detailed checklist to mitigate such risks by separating critical components across different providers. Key recommendations include moving DNS to an independent provider, lowering TTL values, maintaining a live mirror site on separate hosting, and isolating corporate email. Additional steps cover local backups, monitoring, access management, and CDN usage. The guidance differentiates between virtual hosting, VPS or dedicated servers, and website builders like Tilda, while emphasizing compliance with Russian data localization laws such as 152-FZ.
