Optimizing Singapore peering?

[Landy Bible via NANOG <nanog () lists nanog org>]

Hey NANOG,

I realize this is "NA" NOG list, but I assume I'm not the only one
here who is operating a global network.

Context: we have a dozen or so PoPs around the world to serve our load
balancer product. We're using continent-specific prefixes to run
anycast for this. We are on at least one IX at each location, and use
Cogent as our primary transit provider. We'd like to add a real Tier 1
provider at each pop in the future, but In general, this all works ok
right now.

However, Singapore is a problem. We're on SGIX, but we're seeing a
rather high percentage of traffic that originates in Singapore
entering our Tokyo PoP instead. Google Cloud in particular is REALLY
bad, with application latency testing approaching nearly 1 second,
when our typical global latency is under 100ms on an end to end test.
Other SG clouds are bad, but not THAT bad.

My question to the list here is... for those of you who also operate
in Singapore... what would you suggest we do to improve things here?

We're looking at adding Arelion or NTT transit in APAC, but we're also
trying to get PNIs (or even full IP transit) to the big Singapore
networks like SingTel, SingNet, and StarHub, but we haven't had any
luck yet. Perhaps we just don't know the right people.

> From a business perspective our primary concern is latency for our big
customers who are hosted on the clouds in the area, but I don't want
to just ignore our other customers who aren't in the cloud.

Based on my research thus far, my gut says getting transit from
Arelion is probably my best "bang for buck" move, but I'm wondering if
any of you have any insights or wisdom to share about Singapore or
APAC in general.

Thanks All,
Landy
