SingTel Routing in Singapore

Anyone here using SingTel in Singapore?

My traffic from SingTel to the Zscaler ZEN in Singapore hosted at Equinix is taking a very strange route and introducing 40ms latency. In country connectivity I would expect to be sub 10ms.

It looks like it routes out of country (Hong Kong?) as if SingTel and Equinix do not peer in Singapore which would be a little strange.

Tracing route to sin4.sme.zscloud.net [165.225.112.28]
over a maximum of 30 hops:

Trace complete.

Zscaler TAC show me that the return traffic actually routes direct from Equinix to SingTel so the issue is only one way.

Anyone else seeing this and would like to share a traceroute?
