BATS Post Mortem – Carrier Issue

Dear Member,

Please be advised that due to a significant multiple circuit carrier outage in the northeast, at 15:01:34ET on Friday, January 27, 2012, BATS BYX Exchange, BZX Exchange and BATS Options experienced a network disconnect on their primary network links to the SIPs and OPRA. All SIP connections failed over seamlessly to the secondary path. The majority of OPRA connections failed over seamlessly, however a subset were unable to initially connect to the secondary path. The secondary path to the subset of OPRA connections was established at 15:43ET at which time BATS Options was operating normally.
This connectivity issue also affected routable orders through the primary path to another market center on the BYX Exchange and BZX Exchange. These connections automatically failed over to the secondary path. Any stuck orders caught in flight were electronically cancelled.
The secondary site for the BZX Exchange was also impacted as a result of this carrier connectivity issue. This resulted in market data sourced from the secondary site being unavailable from the commencement of the carrier outage on.
All BATS primary site systems are operating normally. Secondary site systems will operate normally on Monday, January 30, 2012.

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