YouTube incident

On 24 February 2008, Pakistan Telecom caused a major interruption of access to the video-sharing website YouTube. Pakistani Government authorities instructed Pakistan Telecom (PTCL) to prevent access to YouTube within Pakistan. PTCL complied by changing the BGP entry for YouTube – essentially updating its local internet address book for where YouTube's section of the internet is. The idea was to direct its internet users to a page that said YouTube was blocked. However, the ISP announced the new route to its Internet link provider, PCCW. PCCW had recently provided temporary access to PTCL in order to restore the nation's loss of internet access due to a previous major submarine cable break event. PTCL began leaking the BGP announcement to PCCW prior to PCCW's completion of the BGP validation and filtering policies process on the newly activated link. This allowed the announcement to propagate to other networks.

Once detected, PCCW immediately blocked the leaked announcement from PTCL and access to YouTube was restored within 2 hours.

All staff in Cascade had transferred to HKT without changing; however, due to the 2011 initial public offering of HKT Limited, some subsidiaries of HKTGH (which HKTGH was a wholly owned subsidiary of HKT Limited) still use the name Cascade or PCCW due to legal and finance reasons, although they are wholly owned subsidiaries of HKT. A mainland China-incorporated "PCCW Cascade Technology (Guangzhou) Limited" (Chinese: 广州电讯盈科萃锋科技有限公司) namesake is a wholly owned subsidiary of HKT Limited.
