I'm sure there are some caveats about interpreting the pretty picture and data this way, but a neat visualization just the same.

"A map of all ~2,100 Swiss municipalities showing which provider handles their official email - grouped by jurisdiction - based on public DNS records." […]

@paulehoffman @msftsecurity @bagder I searched nugget for "ssh" - Yikes! Maybe 99.99% of the results are harmless, but what the heck is all that stuff ... and look at the download counts.

#Hosting provider AlexHost (#AS200019) is raising the price of their low end U1 VPS (1 CPU, 1.5GB RAM, 10GB NVMe) from 4€/month to 6€/month. Two reasons for the increase are:

"The price of RAM has increased."

"[...] abuse of extremely cheap plans has also increased significantly."

Small #hosting provider Servitro (#AS213495) sent out this alert:

"Due to an urgent network issue, we need to replace the subnet 192.209.62.0/24 with a new subnet. This maintenance only affects servers currently using IP addresses from 192.209.62.0/24."

They were leasing this prefix from […]

DNS-OARC The DNS Operations, Analysis and Research Center. DNS-OARC has 38 repositories available. Follow their code on GitHub.

DNS-OARC has officially moved from #GitHub to #Codeberg.

This seems mildly noteworthy to me. They have a number of widely used DNS-related utilities and projects that had been on GitHub for many years.

Contabo (#AS51167):

"[...] we are internally facing sharply rising market prices for state-of-the-art, server-grade components - in particular, high-performance RAM and other critical hardware - as a result of the rising AI demand."

VM prices are going up about 20% in April 2026.

IP4 prefixes for.ir TLD name servers are being announced. TCP/UDP over IP4 queries are getting responses from most of those name servers.

There are inconsistencies between what is in the root and now in ir. The root zone has IP6 addresses for each .ir name server, but the .ir zone currently […]

Net and cloud people, this imay be worth a look? Some hard-coded net resources, temp server listeners, and DNS juju going on here it looks like.

The differences are stark.

Bar plots like these may raise more questions than answers.

Without any y-axis label what are we to make of this? We don't really have a sense of scale.

Are two months on the x-axis long enough to show correlation or just coincidence?

@xabean I've been caught by this a few times on remote systems. Thankfully I've always had the ability to remote console in.

You can set an alias name if that helps.

@jerry In the DNS world there is the concept of newly active/observed/registered domains. This has been used for all sorts of things, from trend analysis, to alerting, to quarantine, to outright blocking.

I wonder if the concept could be applied here, and maybe even just to accounts from […]

A few DoD's BGP withdrawals I looked at are covered by larger prefixes. I am not intimately familiar with these networks, but I think it would be a good guess to say these BGP updates reflect something related to the Israel-US strikes on Iran.

@ricmac archive.org also has an opt-out, but either archive.today seemed to largely ignore those requests or site owners were unaware of archive.today's existence. This could be useful particularly after Google discontinued the cached page feature.
