[sloj]

180.87.105.18 is TATA

That is the US one, so I guess that high is expected.

Seems to be an internal Tata issue in Singapore.

Tata looking glass shows things are fine, there is no jump in latency. On BSNL route to both goes through Airtel and about 76 ms, can't compare unfortunately. Though latency is fine if I check addresses on AS4755 but AS6453 route is crazy like London -> Marseille -> Singapore.
