It's a pretty good way to get the bill paid to be honest I also run a B2B SaaS and I have found that over time the customers who I think are going to be terrible for paying, typically tend to be very good at paying and the customers

Yup, unless that component has been disabled (which is quite rare) or the other side is bird, a bgpd that doesn't buffer anything !

Based on some quick sleuthing, I would assume that the 0xff reserved BGP attribute is likely a huawei quirk. Almost all of the 0xff's visible to bgp.tools (hi) follow the same format as the one in the post, and some of those networks w

Route dampening has mostly fallen out of fashion with networks these days. Most setups were horribly misconfigured and (most) routers are no longer extremely CPU starved as they once were, That doesn't mean that it does not still exist

systemd's resolved commonly uses 127.0.0.53, Given the deployment of systemd I would not really call that a niche cases in terms of volume, but I do agree in general that 127.0.0.0/24 would in theory be enough. However the whole d

Sure you can install basically any EFI+amd64 distro you want, that also has the correct kernel module. I don't really know why you would want do that (though, RHEL based would be a reasonable 2nd option) Performance of the distro isnt

It really depends on how much you know what you are doing, If you stick to: *) IP Routing that would normally "fit" in a vendor switch *) Bridging *) VRFs You will be fine If you try and do some weird stuff then it's best to

In my eyes, MultiModeFibre is on it's way out. The high speed (25G+) does not have good solutions for multimode, and the length limits that physics enforces with multimode mean that it's not "no-brainer" applicable for g

Quiet in the terms of DC grade switching, I'm not sure you could get away with such a switch in a home environment. The 100G optics need plenty of airflow to keep cool so it's not just a case of swapping the fans for something sma
