thank you for reaching out offlist.
We've received our core switching hardware (thank you Arista for donating these) and identified 5-7 potential different sites which we can be colocated, however, we will start with two that are diversely connected with each other. somewhere others can go deploy 1-2 rack deployments, easily.
what do we need now? we will go to Puerto Rico and go rack hardware/servers/cable etc if you have any way to help (you might be living there, etc.. feel free to reach out)
an IX without networks to peer is well not an IX. so if you are able to make deployments using 1-2rack unit servers, or even virtual servers (DNS, etc..) feel free to contact me offlist. We would like to have in general, root-servers, TLDs, CDN caches, etc. these all peer with ix.
regarding costs of ix - we will be following a model where "members share all costs", at the beginning our ultimate goal is to keep these costs to an absolute minimum. Any other recommendations, please feel free to reach offlist. next, I hope to share some peering utilization numbers. <fingers crossed>
