Basically on my own opinion, Explanation for this is that since smartbro is a subsidiary of pldt, pldt uses or should i say leeching with smartbro's inet servers which is at present is not that congested. Connection from selected areas where diverted to this servers for a result of freeing congestion on pldt servers. To prove this theory, Im a subscriber of mydsl but my IP add comes from smartbro. hehehe...
