Engineering notes from the team that runs the Euronodes servers and network (AS199053) in Lisbon and Prague. Real measurements, real problems, and how we fixed them.
In October we moved the first batch of VMs off leased Cogent addresses and onto our own RIPE space, with one DHCP change per VM and no reboots. On 9 November 2026 at 00:00 UTC we moved the rest to another of our own prefixes.
It mostly went the same way. One thing did not, and it is the more useful part of this story.
Hosting benchmarks are usually run on an empty server, the day it is installed. We did the opposite: we ordered our smallest plan on a production node carrying normal customer load, and measured it.
Our Lisbon edge runs a pair of MikroTik routers. VMs use VRRP gateways, so either router can take over if the other one dies. One day the busier router climbed from 60% to 90% CPU with no change in traffic, and FastTrack was barely working.
CVE-2026-99999 is a flaw in the Linux kernel's IPv4 stack, rated CVSS 9.3. It can let a virtual machine break out to its host. On a VPS platform every customer is root inside a guest, so every host was exposed.
There was no workaround. The only fix was the patched kernel and a reboot of every hypervisor.
Part of our Lisbon address space was leased from Cogent. Leased addresses work, but they are not yours: the carrier owns them, and leaving means renumbering every server on them. So we are moving customers onto our own RIPE prefixes, announced from our own network, AS199053.
On 1 October 2026 at 00:00 UTC we moved the first batch of customer VMs to a new /24.
From 1 August 2026, prices for new VPS go up by about 20%. Our entry plan moves from 3.72 EUR to 4.54 EUR per month.
A customer asked on Reddit: "I just got a small VPS. Can I download torrents for my Jellyfin server, or will I get suspended? I won't seed, only download." Here is the longer version of our answer.
We get this question regularly: "Do you offer an anonymous VPS?" The short answer is no, and nobody really does.
A few times a week someone asks "which VPS should I pick?". This is where we would start, even though we are a provider ourselves.
We are Euronodes Ltd, registered in Cyprus, a RIPE NCC member with our own network, AS199053. Our biggest deployment is in the ONI datacenter in Lisbon, the second one is in Prague, with smaller presence in Frankfurt and Madrid. We sell VPS, dedicated servers, storage and colocation.
