 This comes from a [daily snapshot](https://gannet.fish.washington.edu/v1_web/owlshell/bu-github/ghr.log) (`df` plus CPU load) that raven writes to gannet each morning around 7am, not from the live network check above — so it can be up to a day old, and it is flagged if the snapshot itself goes stale. Drives are listed fullest first.

+Health of `gannet.fish.washington.edu`, the lab's Synology NAS, from the [daily health report](https://gannet.fish.washington.edu/v1_web/owlshell/latest.txt) it writes each morning. The server status probers pick up each new report within about an hour of it being written, so this page is at most a day old. It is flagged if the report goes stale. For whether gannet is answering right now, see [Server Status](Computing-Hardware.md#server-status).
