Our servers are currently in the US as that's where the market is (from what we've found, so far). It's something we've thought about and we will be looking at doing international deployments as soon as there is demand.

For API performance, a cloud-based setup does mean an increase in latency, but that is why our solution can be self-hosted too, it's a trade-off that works on a scale, you can start off with a cloud service, with quite straightforward integration and then as your API usage grows look at using Tyk within your own data centers.
