Seems like Softlayer/Network layer having rouitng glitches in Asia.

Their prefix 216.12.192.0/19 is not working in South East. Route goes till
Singapore router and times out there.

I wonder what causes such issues? Clearly issue is within Softlayer's
AS 36351. So is it like broken OSPF inside or iBGP?
