Cboe One Disaster Recovery

Users of Cboe One that are interested in disaster recovery must maintain connectivity to the Cboe Disaster Recovery (DR) site in Chicago, IL. To establish new connectivity to the DR site, contact the Cboe NOC.

The Cboe One US feed that is disseminated from the DR site takes the incoming SIP trade feeds and connects to Cboe PITCH services sourced in the DR site for BZX, BYX, EDGX, and EDGA. The same data sources are used to distribute Cboe One from both the Cboe Primary site and Cboe DR site, so Cboe One customers can fail-over to or utilize the Cboe One feed out of the DR site at any time. However, message content, packet framing, and sequence numbers are not guaranteed to be the same between the Primary and DR sites due to message coalescing differences.

The Cboe DR site is designed to support Cboe One inter data center resiliency in the following DR scenarios:

1. Hardware failure in the primary Cboe One system. Customers always have the option to switch to the DR site at will if they don't want to wait for remediation of failed hardware in the Primary data center to take place.
2. Failover of one or more of Cboe’s equities platforms to their respective DR site. The Cboe One US feed in the Primary site currently only connects to market data for Cboe One US within the Primary site. If one of the exchanges fails over to the DR site, then the Cboe One feed out of Primary site will not be able to disseminate updates from that exchange’s market data feed in the DR site. In this scenario, customers should take the Cboe One feed out of the DR site to regain full coverage.
3. Loss of any of the Cboe One input feeds. Similarly to scenario #2, if Cboe experiences a market data (PITCH/NITCH) dissemination issue for any Cboe One US exchange at the Primary site, but PITCH/NITCH market data is valid for the problem exchange at the DR site, then Cboe One customers have the option to switch over to the DR Cboe One feed to regain full coverage. The same situation applies if Cboe experiences an outage at the Primary site with respect to receipt of SIP feed data. If those feeds are still being received at the DR site, then customers have the option to switch over to the DR Cboe One feed to regain full coverage.
