Shared cache servers on an island's IXP

Hello, I'm trying to find out the best way to consolidate connectivity on an island. The current issues are : - Low redundancy of old cables (2) - Low system capacity of said cables (<=20Gbps) - Total service loss when both cables are down because of congestion on satelite backups - Sheer pr

Hi Jérôme VMs are no go for big content companies except Microsoft. You can run Microsoft CDN on VM but rest of the content will need to be cached. You can actually install this yourself Depending on how much traffic do you have , you may be able to get facebook, youtube, netflix caches i think m

Many CDNs have hardware options for self hosted caches. I think there would likely be concerns about <20G of connectivity to those caches though. With an incorrect setup, you could end up maxing out those links just with cache fill traffic itself. On Thu, Jan 18, 2024 at 6:54 AM Jérôme Nicolle w

Some will work directly on the IX via BGP. Others have to go behind a member of the IX. - Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP - Original Message - From: "Jérôme Nicolle" To: "Mehmet" Cc: nanog@nanog.org Sent: Thurs

Re: Shared cache servers on an island's IXP

Hosting authoritative and recursive dns servers at the IXP would drastically improve the experience of users most of the time. Of course, Stephane considerations are correct and there’s no solution for when global connectivity is lost and responses will stop being sent. Gaël On Thu 18 Jan 2024

I'm actually referring to something like, I've not yet had a system where they have made sense, I mostly deal with either places where I have no say in the hvac or very small server rooms, but I've thought these were an interesting concept since I first saw them years ago. https://www.chiltrix

According to the diagram on page 8 of the presentation on your website at https://www.avinta.com/phoenix-1/home/EzIPenhancedInternet.pdf, it simply identifies 240/4 as CGNAT space. Routing between regional access networks typically doesn't take place when using such space on an ISP network, and mos
