Re: Optimizing Singapore peering?

[Tom Beecher via NANOG <nanog () lists nanog org>]

Always do your homework on who your transit providers connect with and
where. Cheap transit is great, until it carries your bits everywhere except
where you need them to go,

The best thing to do in SG/APAC generally is to do a good analysis of where
you need to get to first, then compare against the available providers to
see where they connect to those destinations. It's not uncommon to need
more than 1 provider to cover all the gaps. Interconnection in APAC is very
fragmented , for a lot of reasons.
