Hi all, I have posted this to the LacNOG list but it seems pretty quite and it involves North America also, so I hope no one minds me reposting here also; I am looking for any guidance and advice people have regarding first time peerings in South America. Currently I am doing some work with a content provider in North America and I want to get them better routers into South America, to South American ISPs. I am looking to get them an interconnect from their NA location to SA, into a PTT IX location in Sao Paulo (they seem to be up there for top IXs in SA, or am I mistaken?). I'm new to the PTT IXs so does anyone have any recommendations about any aspect here, support horror stories, reason to prefer one location for peering over another etc? I see Level3 are in the PTT Sao Paulo location, and we have access to Level 3 already. Is there someone else I should be looking at who is especially good at private routes down to SA, enough to digress from Level 3, or are Level 3 a good choice here? Again, any past experiences are welcome, and recommendations for a different IX or provider any why. Many thanks, James.
