This is currently impacting all of your services to Europe. We  have now received an indication of the ETR for the fault: permitting is  expected to be completed within one week and the repairs are then  expected to take 5 days. The repair vessel has been notified of the  callout and mobilization will occur once permits are received. SEACOM  is continuing to work on additional restoration routes. As options  become available your account manager will be in contact to discuss.  Should you have specific requirements or wish to discuss options please  contact your account manager. We will continue to keep you informed on progress of the repair."}
