all mirrors are too slow

Error message

all mirrors are too slow

What it means

mirror_speed_test benchmarks INTERNAL_MIRRORS against the manifest URL and, after picking the fastest result, bails when the best measured speed minus 1.0 is below 0.0001 — i.e. every mirror's measured speed is at the ~1.0 floor, meaning no mirror responded usefully. The cached mirror selection is left untouched (or unset), so subsequent manifest fetches have no viable mirror.

Solutions

1. Check overall network connectivity; all mirrors failing usually means the machine is offline or behind a blocking proxy/firewall.
2. Retry later — mirror outages (e.g. GitHub raw blocked or CDN issues) are often temporary.
3. Configure a working proxy/VPN so the internal mirrors become reachable.
4. Clear the cached mirror timestamp to force a fresh speed test once connectivity is restored.
