I can't comment on getting PNIs with those networks specifically, I'm not peered with them, but in general, I find that 
getting PNIs is almost always about speaking to the write person, it's annoying, but that has consistently been my 
experience unfortunately.

If getting the PNIs doesn't work out, my advice would be to use the right tool for the job. You don't want a Tier 1 
here, you want to a Tier 2. Tier 1s offer wide (global) but shallow connectivity, meaning they will get your traffic 
from any country to any country, but not much more granular than that in many cases. Tier 2s offer narrow (regional) 
but deep connectivity, meaning they will get your traffic to the exact PoP it needs to get to, but only as long as it's 
in their region.

So in the case of Singapore, get transit from SG.GS. They are consistently one of the best connected networks in the 
world (better than many Tier 1s) and the best connected network in Asia. I know the folks there, can intro you off-list 
if you want (there's nothing weird going on here, I don't work for them, own shares, get commission, or anything like 
that).

If you want to lower your latency in each region my advise would be to get connectivity from a well peered network 
within that region.

I produced stats comparing all the Tier 1s and top 20 best connected non-Tier 1s at the end of last year, you can find 
it here: https://tier1-analysis.53bits.co.uk/part3/2025/README.html.

For APAC, start with SG.GS and try SingTel, if you have to go to one of the more traditional ones, you don't want 
Arelion for Asia, you want NTT/Telstra/TaTa/PCCW.

Cheers,
James.
