Summary of Completed Maintenance

Maintenance yesterday, November 9th, went off without a hitch. This update was to increase trading capacity and improve behavior under high load. A list of changes:

  • Our trading engine was upgraded to a more modern server with faster, newer CPUs. This has improved overall latency and queue depth.
  • Load-shedding has been implemented. If the trading engine’s queue depth grows beyond an internal threshold, new requests will be immediately refused with a 503 until the queue shrinks again. Order cancellations are not subject to this restriction.
  • We have quadrupled capacity on the subsystem responsible for user authorization and API keys. This is a future-proofing measure and is unlikely to be noticed by users.
