Please be aware of the following Planned Maintenance that will be taking place, and
this will affect SAT-3 traffic as detailed below :

Below are the tentative scheduled dates and times :

1. RET on Friday 29 January starting at 10h00 SA time (not traffic-affecting exercise).
This has already commenced as per above.

2. Tentative Restoration Schedule for Sunday 31 January 2010 starting
02h00-17h00 SA time. This will facilitate the restoration of the 94 SAT-3 bearers
to alternate submarine cables (SAFE/SMW3). Please take note that all Telkom SA
Customers on the 94 Restorable bearers will experience physical patching hits for
10 minutes within the associated maintenance window. Unfortunately higher latency
is a characteristic of the restoration route (via Malaysia and India to Europe) and
is unavoidable.

3. Power reconfiguration on Monday 1 February 2010, starting 02h00-08h00 SA time.
This is to perform BU (Branching Unit) reconfiguration in order to normalise the power
configuration on SAT-3. Please take note that all non-restorable traffic will be down for
the full period (02h00-08h00 - SA time). The Telkom SAIX Network will also unfortunately
be affected with a 50% degradation in capacity, resulting in congestion on International
browsing during this period. The Telkom SA SAIX notice board will be updated.

4. Tentative Normalisation Schedule 2 February 2010 starting at 02h00-17h00 SA time. This
will facilitate the Normalisation of all 94 restorable bearers from the SAFE/SMW3 routes
back to SAT-3. Please take note that 10 minute patching breaks will be experienced
during this period.

Summary of effect to TSA traffic:
Restorable: Will see physical patching hits on the following dates: 31 January 2010 and
2 February 2010, within the approximate maintenance window (02h00 to 17h30 SA time).
Higher latency will be experienced during the restoration period.

Non-Restorable: Traffic will be down for the duration of the Power Reconfiguration exercise
on Monday 1 February 2010, starting 02h00 SA time, until the power has been successfully
reconfigured. This usually takes between 2 to 6 hours. Non-Restorable traffic returns
automatically after successful power reconfiguration has been performed.
