About more than a week ago, TM reported outage of one of their International Links linking to US and Europe which causes slow International traffic.
At midnight, TM’s Twitter @TMCorp had made an announcement that this has been restored and all international connections should be working normally by now. This comes a day before its original estimate dateline of 2nd May.
Those continue to face the problem are urged to report to TM for further assistance. More details on the announcement here.
