Internet users might experience “intermittent degradation” in service quality and connectivity, the authority said in a statement.

“Trans World Associates (TWA) is coordinating with the SMW5 Consortium to identify the root cause of the fault and determine the estimated time for restoration (ETTR),” it said.

“In the meantime, internet traffic is being rerouted through alternate international links to minimise the impact and ensure service continuity to the greatest extent possible,” it said.

“PTA remains in close coordination with the concerned stakeholders and will continue to monitor the situation to facilitate the earliest possible restoration of normal internet services across the country.”

DIRBS services suspended July 3-6 for system upgrade

In a separate statement issued earlier in the day, the PTA said it was upgrading the Device Identification, Registration and Blocking System (DIRBS) to “better serve both the general public and commercial entities.”

“The upgraded, in-house developed system will simplify the device registration process for all users,” it said.

“Due to this scheduled upgrade, the DIRBS portal (dirbs.pta.gov.pk) and all related services will be temporarily unavailable from July 3, 2026, 5:00pm until July 6, 2026, 4:00am.”
