+# A separate pack rather than three more entries above, because the Cloudflare
+# API only orders and deletes certificate packs — it cannot update the host
+# list of one. Editing hosts on the pack above therefore destroys the live
+# certificate and orders a replacement, and that certificate is what serves
+# every customer hostname for Ogmios v6, Kupo, Blockfrost and UTxO RPC. This
+# way the worst case is a rejected order rather than an uncovered zone.

+# The unauthenticated endpoint cardano-{network}-v7.ogmios-m1.dmtr.host needs
+# no entry: *.ogmios-m1.dmtr.host above already covers it.
