Since when did Swank ( or is it known as digital campus? ), the movie streaming site used by #HigherEd, start playing YouTube ads before ( and maybe during? ) the movie?

Our IT department just got this excellent spam from an AI vendor. Apparently we have been running our own server room since 1862! I was not born yet, so I'm very curious what "servers" we were hosting back then. Maybe they should run their AI through another AI […] [Original post on ipv6.social]
Screenshot of a spam message that reads:

Gustavus has run its own campus server rooms since 1862, so | imagine the hardware has piled up across buildings over the years.

| am Peter Langford at PODTECH. We build datacenter management software with Al-driven monitoring. One university IT team cut unplanned outages 40%
rooms.

We could run the same read-only assessment for Gustavus, done in about two weeks. If it shows nothing useful, you owe us nothing.

Would a short reply be easier than a call to see If this fits?

Best,

Today I saw a post on Hackaday about "UDP broadcasting" and #IPv6. Only that it barely touched upon UDP or broadcasting, and mostly served to reinforce long-dead or never-true assumptions that devs tend to have #IPv6. One citation is to a "2020 rant" that can be summarized as: addr6 too long […]

Apparently Cloudflare sees nothing wrong with that website. Looks like the site changed and when I go there now, it's completely different. Now I just get redirected to random websites.

Here is my somewhat regular, beginning of the school semester, post about #IPv6 vs #IPv4 traffic on our college campus. IPv6 traffic is still generally twice that of IPv4. Maybe a little more IPv6 now than this time last year.

Time for another very irregular regular update on #IPv6 compared to #IPv4 usage on a dual stacked college network. As you can see from the graph, for most of the past 24 hours, incoming IPv6 traffic is significantly higher than incoming IPv4 traffic. This has been the case for many years now.
