Status / Diagnostics
This page helps diagnose whether SWPC is reachable from this server and whether cached data is being used. If outbound HTTPS is blocked, the dashboard will still run but may show blanks until the cache is warmed.
Upstream Reachability (quick probe)
| Path | OK | HTTP | ms | bytes |
|---|---|---|---|---|
| /json/planetary_k_index_1m.json | yes | 200 | 184 | 28003 |
| /json/f107_cm_flux.json | yes | 200 | 181 | 22838 |

Common causes if probes fail
- Outbound HTTPS blocked by firewall/proxy.
- TLS trust/CA bundle not configured for PHP cURL (see hamweather/certs/README.md).
- cURL not enabled; PHP stream HTTPS blocked by configuration.
- Temporary upstream outage.
