And now for something completely indifferent

I will now take a break from my ongoing struggles to make Blazorise play nicely with Open ID authentication so I can read these:

And finally, WGN confirms we hit back-to-back record temperatures Wednesday and Thursday, both tied for 11th warmest December day in Chicago history.

Come on, Xfinity

I've had intermittent Internet all morning for no reason that Comcast/Xfinity can tell me. Everything I do professionally requires an Internet connection.

I am displeased.

Fun start to the day

My 8am meeting with colleagues in London had to wait until 9:30 because Comcast screwed the pooch this morning:

Reports indicate the system was down, or at least unsteady, in areas stretching from Chicago to Philadelphia, New Jersey, and South Carolina. Looking at DownDetector, issues had been reported earlier in the Bay Area, but it’s unclear if those are connected to the problems people saw this morning.

Comcast has released a statement regarding the outage. According to a spokesperson, “Earlier, some customers experienced intermittent service disruptions as a result of a network issue. We have addressed the issue and service is now restoring for impacted customers, as we continue to investigate the root cause. We apologize to those who were affected.” It appears that most of the people who reported problems have confirmed they’re back online. There’s still no word on exactly what caused the problem or how many people were impacted at its peak.

In Chicago, the outage affected thousands of people from about 7:30 to 9, by which time I'd already relocated to my company's Loop office.

Oh, and on the day before a trip, my bank called to let me know their fraud department killed my primary credit card. They hope the new one arrives before I leave for the airport.

Yay.

How Facebook went down today

Cloudflare explains:

BGP stands for Border Gateway Protocol. It's a mechanism to exchange routing information between autonomous systems (AS) on the Internet. The big routers that make the Internet work have huge, constantly updated lists of the possible routes that can be used to deliver every network packet to their final destinations. Without BGP, the Internet routers wouldn't know what to do, and the Internet wouldn't work.

The Internet is literally a network of networks, and it’s bound together by BGP. BGP allows one network (say Facebook) to advertise its presence to other networks that form the Internet. As we write Facebook is not advertising its presence, ISPs and other networks can’t find Facebook’s network and so it is unavailable.

The individual networks each have an ASN: an Autonomous System Number. An Autonomous System (AS) is an individual network with a unified internal routing policy. An AS can originate prefixes (say that they control a group of IP addresses), as well as transit prefixes (say they know how to reach specific groups of IP addresses).

At 1658 UTC we noticed that Facebook had stopped announcing the routes to their DNS prefixes.

We keep track of all the BGP updates and announcements we see in our global network. At our scale, the data we collect gives us a view of how the Internet is connected and where the traffic is meant to flow from and to everywhere on the planet.

A BGP UPDATE message informs a router of any changes you’ve made to a prefix advertisement or entirely withdraws the prefix. We can clearly see this in the number of updates we received from Facebook when checking our time-series BGP database. Normally this chart is fairly quiet: Facebook doesn’t make a lot of changes to its network minute to minute.

But at around 15:40 UTC we saw a peak of routing changes from Facebook. That’s when the trouble began.

So, someone at Facebook may have applied a router update incorrectly. And as of now, they've corrected the problem.

First Monday of October

The United States Supreme Court began their term earlier today, in person for the first time since March 2020. Justice Brett Kavanagh (R) did not attend owing to his positive Covid-19 test last week.

So how did facebook.com disappear from root DNS, the day after 60 Minutes aired a segment on Haugen?

How is it already 4pm?

I have opened these on my Surface at work, but I'll have to read them at home:

Finally, Empirical Brewery has a new line of beer that supports Tree House Cats at Work. I'll try some and let you know.

Light, air, dog

The environmental change I alluded to yesterday went much more smoothly than anticipated.

When I moved to my current place, I put Inner Drive Technology World Headquarters (IDTWHQ) in the room that most clearly said "office," the one off the kitchen with all the built-in bookshelves and the A/V stack the previous owners left behind. It faces south, but it has bay windows covered in ivy, providing subdued indirect light in the summer and lots of direct sunlight in the afternoon from October to March. While the bay windows provide some ventilation, the room gets a bit stuffy when they're closed, and doesn't really get much airflow when they're open. Also, the geometry of the room never quite worked with my desk. I had to squeeze around it to get into my chair, making the whole thing feel a bit constraining.

Add in 3-5 days of working from home every week, with my work laptop and secondary monitor occupying a hunk of real estate on the desk while dropping wires and power cables on the floor between the door and Cassie's bed, and the whole thing has felt really cramped for the last 18 months:

That, my friends, is bad feng shui.

Meanwhile, my easternmost room, overlooking the leafy side-street I live on, naturally became a sunroom:

I mean, light, air, and about half the time a dog on the couch? What's not to love? In fact, now in the second summer of working from home 60% or more, most days I wanted to sit on that couch with Cassie and read—especially when the weather permitted me to open all nine of those windows.

So, with a little help from Comcast to fix the cable running into my living room, yesterday I moved my office into the sunroom. Even with my work crap still occupying the same hunk of real estate, it just looks and feels so much better:

And the office? It became a sitting room:

I don't know how much I'll actually sit there, but its proximity to the kitchen means that when I entertain, people will use it for kitchen-adjacent overflow.

Cassie, naturally, freaked out a bit, and it took some coaxing for her to get back on the couch (probably because it was in the wrong place!). But as I write this, she's in the room with me, psychically commanding me to take her outside.

I don't understand why I didn't do this last year. It would have made the pandemic lockdown a ton more enjoyable. I mean, it only took me six years to configure my place in Lincoln Park correctly, but that had to do with the physical constraints imposed by having an entire server rack in one corner of the living room in an era before gigabit wi-fi. (The server rack had to go next to the POTS line jack because I used a DSL, and running a network cable through the walls to the other side of the living room was the only real option.)

This room really does feel better. And tomorrow, after Chicago's fever breaks, I'll open the windows.

Tweaking the environment

If all goes as planned, in about half an hour a Comcast technician will make a change to my service here at Inner Drive Technology World Headquarters that will, in turn, result in Cassie experiencing some anxiety. I don't want to cause doggy angina, but if Comcast moves my primary cable connection from the room it's in now to the room I want it in, then I'm going to spend the subsequent two or three hours moving furniture.

Updates and art as conditions warrant.

Relaxing weekend

Cassie and I headed up to Tyranena Brewing in Lake Mills, Wis., yesterday to hang out with family. Today, other than a trip to the grocery and adjacent pet store where Cassie picked out an "indestructible" toy that now lies in tatters on the couch, we've had a pretty relaxing Sunday. I thought I'd take a break from Hard Times to queue up some stuff to read tomorrow at lunch:

I will now return to Dickens, because it's funny and sad.
