I noticed you use cogent, aside from some peering with Verizon and others, are you sure your transit capacity is available by cogent and he? Had issues at choopa and only peer with them
We have a minimum of two separate bandwidth providers into each datacenter. Depending on which datacenter your data is in, it is some combination of: Cogent, AboveNet (now called "Zayo"), Wave, Century Link, and maybe one or two others??
The reason we always have two separate bandwidth providers is that any one provider is basically guaranteed to be offline at least 5 minutes a year, and there is a 30% chance any one provider will be offline for two hours once a year. But it is highly unlikely TWO providers will be offline at the same time at any point.
We have three separate datacenters, but any one file you store will be in one datacenter. We have two datacenters in the Sacramento region (about 30 miles away from each other) and one datacenter in Phoenix. So depending on which datacenter your file is in, your network path might change to use a different provider. We are also adding brand new datacenters in 2018 in new regions (like Europe) so that will probably mean new and different network providers.
