Description

NSE extends the migration deadline for self-service connectivity links from Sify's Kohinoor-Kurla POP to the new Parle POP until EOD May 29, 2026. Members using self-service links must complete migration by this revised date to maintain trading connectivity.

Summary

NSE has extended the migration deadline for self-service connectivity links at Sify’s Kohinoor-Kurla, Mumbai POP to EOD May 29, 2026. This is a continuation of earlier circular NSE/MSD/73970 dated April 29, 2026. The original discontinuation date was May 15, 2026. Members who have not yet migrated their self-service links to the new Sify Parle POP must do so before the revised deadline to avoid disruption to their trading connectivity.

Key Points

  • The migration deadline for self-service links at the Kohinoor-Kurla, Mumbai POP has been extended from May 15, 2026 to EOD May 29, 2026.
  • Only self-service links are covered by this extension; managed connectivity links were subject to the earlier deadline.
  • Substantial progress has been reported by TNI Sify for self-service link migrations, prompting the extension.
  • The new POP location is Sify Parle, Mumbai.
  • After May 29, 2026, the existing Kohinoor-Kurla POP will be permanently discontinued by Sify.
  • Members can contact TNI Sify using the Annexure 1 – Sify Handbook for queries.

Regulatory Changes

No new regulatory changes. This circular updates the operational timeline established in NSE/MSD/73970 (April 29, 2026) by granting a final extension of the POP migration deadline for self-service links only.

Compliance Requirements

  • All trading members subscribed to self-service links at the Kohinoor-Kurla, Mumbai POP must complete migration to the new Sify Parle POP by EOD May 29, 2026.
  • Members are solely responsible for procuring and maintaining their network architecture, assets, and connectivity.
  • Members should refer to Annexure 1 – Sify Handbook for TNI contact details and migration support.

Important Dates

  • August 5, 2025: Original announcement of POP migration from Kohinoor-Kurla to Parle.
  • April 29, 2026: Circular NSE/MSD/73970 issued with migration instructions and May 15, 2026 deadline.
  • May 15, 2026: Original discontinuation date for Kohinoor-Kurla POP (superseded for self-service links).
  • May 29, 2026 (EOD): Revised and final discontinuation date for the Kohinoor-Kurla POP for self-service links.

Impact Assessment

This circular has high operational impact for NSE trading members who use self-service connectivity links via Sify at the Kohinoor-Kurla, Mumbai POP. Members who fail to complete migration by May 29, 2026 will lose connectivity to NSE’s trading systems, directly impacting their ability to trade. The extension provides additional time but is explicitly stated as final, meaning no further extensions are expected. Members should treat this as an urgent action item. NSEIL disclaims liability for any connectivity failures and places full responsibility on members to ensure timely migration.

Impact Justification

Failure to migrate by the revised deadline will result in loss of trading connectivity to NSE, making this operationally critical for affected members using self-service links at the Kohinoor-Kurla POP.
