This notice effects only ISPs serviced by SMW4 which would include Streamyx, Singtel and several Indian ISPs.
The repairs on SMW4 off Mumbai which began yesterday on the 23 May 2010 is expected to be completed by the 27 May 2010.
The cable repair ship has arrived and is performing upgrades as planned.
While this repair work is underway, disruptions to connections to Europe and East Coast of US is expected to continue. However, due to rerouted traffic, congestion is expected to also occur on the remaining routes to other international destinations.
Please note that this is strictly not a TM fault as the SMW4 is maintained by a consortium but I have a feeling that TM has not subscribed to sufficient uplinks to successfully failover properly.
