The maintenance, which had been planned for the first two weeks of January 2013, was completed ahead of schedule on Monday.
TEAMS chairman, Bob Collymore said this was due to steadily favourable weather conditions at Mombasa off-shore.
The actual downtime of the system was expected to be from January 3 to 15.
He however says the remaining maintenance which is expected to end in April this year will not affect services.
“The preventive maintenance works have been designed to reduce chances of cable damage by external aggressors, following the couple of cable cuts experienced by TEAMS cable at Mombasa, early last year,” Collymore said in a statement.
It is estimated that the preventive maintenance works on the TEAMS cable, including costs for temporary traffic restoration via other cables during the TEAMS cable outage, will be about Sh480 million ($5.6 million) excluding loss of business as a result of heavily constrained bandwidth supply to contracted customers.
“We would like to sincerely acknowledge the understanding and support of our esteemed customers, throughout the preventive works on the TEAMS cable,” Collymore added.
The TEAMS cable system is the premier undersea cable system serving the entire East African region.
Besides the Government of Kenya, the other shareholders in the TEAMS consortium include Safaricom, Jamii Telecom, Wananchi Group, Essar Kenya, Kenya Data Networks, Access Kenya, Telkom Orange and Bandwidth & Cloud Services.
