How are status pages for major CDNs and major backbone providers designed to be up even though the provider is down?
In: Technology
The computational requirements for a status page are extremely low compared to a full website such as e.g. reddit or facebook. It’s extremely cacheable, lightweight, and read-only. There’s no user authentication or policy enforcement logic. It’s also, for obvious reasons, hosted on separate infrastructure from the main site.
Furthermore, even during an outage event, a status site is going to receive less traffic than the actual site, since only a more savvy subset of the users will bother checking the status page.
