Post Mortem - BATS BZX and BYX Equities Intermittent Network Issues

February 27, 2013 17:29:36

Please be advised that the intermittent connectivity issues early this morning on the BATS BZX and BYX equities exchanges were a result of a network configuration change made the previous evening. Network routing issues within BATS network infrastructure resulted in sporadic Member disconnects to TCP based order entry and market data feeds which were primarily resolved at approximately 9:20AM ET. After that time, certain Members continued to report isolated issues on specific TCP ports. BATS worked directly with the few remaining impacted Members on their port specific issues and as of 10AM ET, all issues were resolved.

Please contact the BATS Trade Desk or your Director of Sales with any questions. Thank you for your continued support of BATS.
