Scheduled Customer Port ACL Update

Dear Member,

On the following dates, TXSE will be updating the existing access-control configurations on customer-facing ports. No service interruption is expected.

Friday, August 14 — Disaster Recovery (DR)

Equinix DA11 — Dallas, TX

Equinix CH1 — Chicago, IL

Friday, August 21 — Production

Equinix NY4, NY5, NY6 — Secaucus, NJ

The update is intended to optimize existing network access-control configurations and does not involve changes to Member connectivity architecture or routing. Member connections and BGP sessions are expected to remain established.

While TXSE does not expect these updates to impact Members, the Exchange recommends that Members validate their applicable connectivity during the scheduled Saturday production tests on August 15 and August 22.

If you have any questions or experience connectivity issues during or following the maintenance, please contact noc@txse.com for assistance.

Sincerely,

TXSE Market Operations
