Please help me figure out what broker will work best for latency arbitrage and what server I should use for social virtual private servers?

For latency arbitrage, your broker choice is secondary to your technological setup, as you'll likely need direct market access (DMA) through a specialised prime broker. The critical factor is co-location: placing your servers physically within the exchange's data centre to minimise latency. Focus on brokers that offer this service for your target markets (e.g., NY4 for US equities).

Regarding social virtual private servers, this is a separate, consumer-grade need. For hosting game servers or community platforms, providers like DigitalOcean, Linode, or Vultr offer high-performance Virtual Private Servers (VPS) with low-latency global data centres, suitable for a smooth social experience.
