Now Telewest customers have received recent speed increases, now according to the Cable Forum so are NTL.

According to their sources from June 1st NTL will upgrade it's customers speeds for free, current 2Mbps customers will double to 4Mbps and also see the upload doubled to 400Kbps.
Those on the 10Mbps will see their package changed to an 'unlimited' one to being it into line with NTL's other offerings.

While some may think giving customers an 10Mbps unlimited connection maybe verging on suicidal, NTL are not adverse to slipping in traffic shaping without any notice. Although this has since been reversed it may not be long before it's back on the agenda.
