Yeah, you should really be getting 10x the speed that you are.
According to TPG maps:
Line of sight distance: 231m. Possible cable distance: 393m.
So basically, you are next door to it
Yeah thats about what I was getting at St lucia, hope to get a lot more now because I'm closer to the exhange (although not as close as colin, about 600m line of site for me, 1-1.2km cable distance)
