A new IPv6 milestone!
28th of March more people visited Google services using the IPv6 protocol than the IPv4 protocol for the first time in history.

It's confirmed. Ukraine will receive Swedish Gripens E, who recently locked on to the invincable F35.
Our support and long term development and cooperation will continue not only now but long after the war . We stand with Ukraine, today and onwards
Our case study with Datapacket is now published. Here you can read some interesting details on the Palworld chaos-weeks of early 2024, that time we got hit (and survived) a 2Tbit/s DDoS attack and other interesting bits of how we operate our global game hosting platform.
"Even a single millisecond matters in competitive gaming. Players can feel it. With DataPacket, we know the routing is optimized and any bad ping issues get solved." —Svante Boberg, CTO at DatHost
We make sure that players worldwide in competitive titles can focus solely on the game while we handle the infrastructure behind it.

During Tuesday 49.84% of all traffic hitting Googles edge was IPv6.
Any week now IPv4 will be the second most used protocol to access Google services.
Do you try to hide your access points or make them part of the medieval decoration? 😄

I see 1000250 IPv4 prefixes. This is 368 more prefixes than 6 hours ago and 1879 more than a week ago. 61.78% of prefixes are /24.
Blown away of how useful eBPF is for ops.
I had a simple bash script that checks interface counters and calculates incoming PPS to detect DDoS on my servers.
But got a lot of false positives when the server was doing updates and downloading stuff in 10Gbit.
I switched to instead only measure incoming UDP and ICMP packets by having my bash script poll /proc/net/snmp.
But this was only counting packets actually allowed, traffic blocked by my firewall is not counted here so a lot of DDoS failed to be detected.
