# archive.apache.org throttles aggressively and a wedged connection produces
# zero curl output — CI builds hung here for 10-30 min (flink-smoke #213/#218/
# #219/#220 lanes). The speed guard aborts any transfer crawling below 64 KB/s
# for 60 s and retries, so a throttled mirror fails fast instead of hanging.
