My guess is throttling or shaping at VF gateway and or over subscription on international links, more customers VF ex IHUg and TCL share same pipe? General surfing to NZ sites web is also often slow and Skype runs like a pig at times too.
The overall value of my naked cable service is becoming much less attractive with VF these days, pay $65 for 40GB when the current VF 12 month offer is $85 for phone/perks, VDSL BB and 80GB of data. Overall performance, mediocre VF customer service and getting really poor value in data allowance on HFC is making a switch of ISP more likely. Not much reason to stay on VF HFC now, Snap VDSL or Fibre looks much bettter these days?!
Do any other in-home HFC users think the same way?
