It's working again. Got some direct responses overnight and this morning 
(in my timezone) those IPv4 prefixes are no longer being announced 
through AS23033. All four through AS23033 were looped, effectively 
causing a full outage from my perspective in the US, but I likely would 
have never known if I didn't have a customer using domains under .co.id.

IPv6 is still broken/looping, 2001:DF5:4000::/48 with path 7018 1299 
23033 132647.
