I make networking, Wi‑Fi, security, and infrastructure easier to understand without making it boring.

If you’re learning networking, building labs, studying certs, troubleshooting weird outages, or trying to understand what actually happens in production, you’re in the right place.

Damnit.

[Microsoft @Microsoft]

We are deeply sorry for the disruption this incident has caused our customers and partners. We know the trust they place in our services and take that responsibility extremely seriously. We are seeing broad recovery and stability across our services.

This was a technical issue not related to cyber or AI / agents. The incident was introduced by an issue during an earlier network capacity upgrade that surfaced following a recent network change. We have addressed the underlying issue and continue to restore service to remaining customers and regions.

Given the scale of demand, we restored services gradually, validating stability at each stage. While this took longer, it helped ensure a stable restoration.

We will provide a full post-incident report once our review is complete.

Outlook and Teams went down today and I had two reactions.

Network engineer me: This is going to a be ton of tickets explaining the same thing over and over again.

Content creator me: finally, the one day normal people will sit through me explaining DNS 🤣

It’s not the network 🙌

[Microsoft 365 Status @MSFT365Status]

The servers we returned to service can become unresponsive again once they receive traffic; we're analyzing diagnostic data to determine what's triggering the behavior. In parallel, we're temporarily limiting which types of traffic can reach the affected infrastructure in some locations. Additionally, we're rebuilding a subset of affected servers using a previous configuration to validate if this prevents them from becoming unresponsive. More info under EX1550543 and MO1550821 in the Microsoft 365 admin center, as well as https://t.co/pYdahqxDv3 if the admin center is not available to you.

Hot take from the podcast: the line between network security and cybersecurity is paperwork.

Security folks, I'm ready. Who owns the firewalls where you work? (with @gkavelines)

@NousResearch @Teknium I run Hermes 24/7 as the manager for my creator business: inbox, sponsors, analytics and my calendar. I missed the iOS beta before it filled up. Any chance I could grab a spot? Happy to send detailed feedback.

How many hours does your phone really get on one charge these days? Does Wi-Fi drain your phone battery? Tell me yours.

Be honest. Have you ever clicked that Write with Siri button on purpose? RemoveMacAI is free and the code is open, not from Apple, so read what it does before you run it: https://t.co/DtdZXvvTGh. How to remove Apple Intelligence from macOS 27 and get your storage back.

Does your web host know about this one yet? If you run anything on PHP, did the October 21 update land, or is your host still quiet?

The ping works. The file doesn't. Ever had a VPN do this to you? What was the fix?

[Kevin Nanns @AdjacentNode]

How many devices do you think are on your home network right now? Guess first, then go count.

Can you answer this entry-level networking interview question? Flood or drop? Best answer in the replies.

Be honest, did you think your router knew the whole way to the website?

[Kevin Nanns @AdjacentNode]

What are you building right now that nobody knows about? Reply with it. Be public.

@thedatabunny More like a controlled falling car lol

@Mkutka I’m all for fun projects. This is not that. I love technology and its advancement. But I think flying cars and space are not where our investments should be going.

[Kevin Nanns @AdjacentNode]

Cool. I'd use this never. How about we solve problems that we actually have?

What’s the most useless thing anyone has told you while your internet was broken? Mine is “I can ping it.”
