Are you sure it was about poor routing to Singapore and not poor routing to networks in EU?
The reason I ask is that a majority of connectivity has been lost to EU and EU > India is mostly via US > Singapore now.I see high latency on this route for that reason but so far haven't seen packet loss or routing issues with Singapore.
Thanks.

For what it's worth we have a provider in India for an anycast network
who gave us a similar answer when we ticketed them about poor routing to
Singapore.
