Washington datacenter is Softlayer. They peer with US-East-1. Latency tends to be < 1ms.
SG datacenter is also Softlayer. While I don't think they peer directly with AP-Southeast-1, latency in SG tends to be 2-8ms (you know, it's a super small country with only a few carriers). From within SG, latency to any SG location will be 50x-100x better than US-East.
The only location that's really off is Ireland -> France..which can explain some, but not other (most) cases.
- rahimnathwani 13y agoThe latency B<->C doesn't inform you about the latency difference between A<->B and A<->C. The traffic may take different routes on its way from A, depending on peering arrangements and traffic conditions. Real-life example: I live in China, and passing traffic through a VPN in Singapore to which I have low latency can speed up (lower latency and better bandwidth) connections to some hosts. Ping times from my domestic ADSL connection to that host are about 90ms because they have direct peering with PCCW. Other hosts in Singapore can be 200ms or more away, even though all of them are <10ms away from each other.
