Choosing an RPC Provider for a UK-Based Team

Teams in the United Kingdom often assume the nearest data centre defines RPC performance. In practice, Solana confirmation times depend on validator geography, your transaction patterns, and how aggressively you batch reads.

For local development, a free public endpoint is adequate if you throttle requests and cache blockhash queries. Production workloads need written SLAs, authenticated keys, and a secondary provider configured before launch day.

We compare providers using a simple matrix: requests per second under burst, websocket reconnect behaviour, historical getTransaction availability, and invoice clarity. Price per million requests alone misleads teams that poll account state every slot.

Schedule a monthly five-minute check: send the same memo transaction through primary and fallback endpoints and record confirmation latency at a fixed UTC hour. Trends appear before users complain.

Document who on your team rotates API keys and who receives provider status emails. RPC incidents at 2 a.m. go smoother when the on-call engineer already knows which dashboard to open.
