I have to change at least one of my uplinks because of it, which one is better to drop, HE or Cogent?
Question: Why would you have to drop one of them? You have no problem if you have both.
Because of money, isn't it? I don't want to pay twice!
Completely makes sense--you want to get the most value possible for the dollars you spend, which means you want to choose upstream providers that give you the most complete view of the internet possible.
So as this is not a bug, but a long time story - I relized for me as a cutomer connectivity from both Hurricane Electric and Cogent is a crap. So people should avoid both, and buy for example from Level3 and NTT, which do not have such problem and do not sell me partial connectivity without any warning before signing the contract.
I'm just a IP transit customer, and I don't give a something for that wars who is the real Tier1. I just want a working service for my money instead of answering a hundreds calls from my subscribers!
So, for you, the choice is going to come down to a comparison of how much each provider charges vs how much of a headache they're creating for you in terms of partial reachability problems. While bigger entities like Level 3 and NTT will give you fewer reachability headaches, they're also likely to charge more; and you don't want to put all your eggs in one basket. So, hypothetically speaking, if Level3 and NTT both charge $2/mb/s/month, and Cogent and HE charge $0.75/mb/s/month, you might find that you get a more cost-effective blend by getting 3 circuits, one each from Level3 OR NTT, and Cogent, and HE, for a total cost of $2+$0.75+$0.75, or $3.50, instead of the other option of buying two circuits, one each from Level3 and NTT, which would be $2+$2, or $4. Yes, I realize this is completely contrived hypothetical set of prices, but the point is only you have the knowledge of how much each provider is charging you; take that information, do a few searches in your favorite search engine for "$PROVIDER peering dispute", and see which providers have the best and worst histories as far as getting into peering disputes, and then choose accordingly. It would be nice if there were a rating system for ISPs that would make it easier for smaller companies to know if they were buying from an "A" rated ISP vs a "C" or "D" rated ISP, somewhat like restaurants that have to post their department of health scores visibly. However, without any overseeing entity that would provide such a rating service, for now it's up to each buyer to do their own research to decide which ISPs are safer to work with, and which ones are riskier. Best of luck making the right choices! Thanks! Matt
