Even 23 years ago, not quite the flex. Remember, SQL Slammer that took out / degraded large chunks of the internet? That vulnerability had been fixed in a patch released 6 months prior to that incident. -----Original Message----- From: Tom Beecher via NANOG <nanog@lists.nanog.org> Sent: Wednesday, February 25, 2026 2:41 PM To: North American Network Operators Group <nanog@lists.nanog.org> Cc: Tom Beecher <beecher@beecher.cc> Subject: Re: OT: Routers with highest uptime Yeah, not the flex it used to be. If you publish a device's uptime, it's not hard to infer what OS might be on it, and know exactly how you can exploit that. Also agreed with Patrick, if you have any routers in a lab, those are the ones that I'd expect to be updated MORE frequently, not less.

I... umm... have you consider applying security patches on these any time in the last 10+ years (I'm really not taking the time to do the math here)?
Best practices are simply not to leave a system up unpatched that long anymore. This is why Netcraft took that metric down. It encouraged a perverse incentive.

Hi NANOG,
in the past there was the Netcraft website which showed publicly "Servers with the highest uptime". Sadly that site apparently doesn't exist anymore.
I'm wondering what are the routers worldwide with the highest uptime. :)
I'll make a start. 2x Juniper M7i lab routers running BGP + VRRP:

Is that good or "like nothing"? :)
