Where do internet providers get the internet they’re providing?
In: Technology
Most people will connect through an ISP who is a Tier 3 provider. Tier 3 providers are buying capacity off of Tier 2 (for local) and Tier 1 (for international) providers. They can run there own data center which will include the hosting for their email servers and websites but many ISPs are outsourcing even that nowadays. Tier 2 networks will have peering (i.e. free) or interconnect (i.e. cross payments) agreements with other networks within the country to provide access to what is essentially the local internet. Tier 1 networks will interface with the international data cables.
So essentially if you are setting up an ISP you need to have an agreement with a telecom provider to supply the last mile access to the client, agreement with a Tier 2 network for local bandwidth and Tier 1 for international.
