Dear Customer,

Please take note of a Liquid Emergency Change Scheduled ALONG ZUURFONTEIN  NEAR THE BRIDGE AT THE GARAGE on the 22nd June 2025 from 07:00 - 18:00. We need to remake the joint that is in a bad state, causing high losses along Zuurfontein.

IMPACT: Services Highlighted in red will be down for a maximum duration of 10Hrs, other services will experience an intermittent 50ms switching hit.

Affected Services:

CT1 - JB1 - Liquid

Reason For Change

To remake the joint that is in a bad state, causing high losses along Zuurfontein.

Implementation Plan

1.            New cable already installed.

2.            Cables will be prepared after into new fibre joints.

3.            The newly installed cable will be tested for quality use.

4.            Cut the old cable and prepare it into the new joint.

5.            Splice the cable as per service priority.

6.            Continuously confirming with both IP NOC for service restoration

7.            Splice the rest of the fibres once all workers are through.

8.            Final confirmation with both NOC on completion.

Rollback Plan:

System(s) will be cut on new cable as per priority and service affecting.

OSP will continuously confirm during and after the cut over with both IP and SDH NOC.

Should there be any system which is still down after the planned work execution, then it will be treated as fault.

Fibre fault diagnose process will kick in to restore the affected services. End to end test will be done to check fibre conditions.

The test will be performed between the applicable POP and the jointing site. OSP FST will ensure that all links are up before parting site.

Overview : Engineers will be performing troubleshooting with Firewall vendor on the HA set of firewalls.

Impact : All services traversing the firewalls will be affected.
