The main phone company (and Internet provider) in Guyana has apparently taken action against Skype. There was a comment on a previous post that said:
GT@T in Guyana has just blocked Skype. Says it is losing money
A little searching turned up this article, which says:
Here’s what I received from my server today: “GT&T has informed us today that all VOIP calls transmitting their internet backbone are blocked or degraded. The network policy was implemented today at 3:00 P.M., December 2, 2008.”
Bummer. I wonder if they’re claiming they don’t have the bandwidth, or if they’re open about the fact that Skype is really destroying their phone business? Has this happened anywhere else, does anyone know?
