# The BCNR record on hephaestus.x currently points at the VPS via `ip:` only,
# so users route through this VPS. This script keeps a parallel copy on Sia
# for disaster recovery: if the VPS dies, updating the BCNR record from
# `ip:` back to `s3:"bns/hephaestus.x/"` (single Argus CLI call) restores
# service from the Sia bucket in the time it takes for one BCH transaction
# to confirm on chipnet.

# Runs on the p2pexchange VPS via systemd timer (hephaestus-x-sia-sync.timer).
