is that a good idea? 

 I have seen in the past one slow drive on  your bus can drag down the others.   I suppose it depends on how they wire the bus on whatever board you get, but i have seen it.

A quick search suggests to SET so_linger with a small/zero timeout
just before calling close(). This will have the server deliver a RST
TCP packet, which bassically equals to sending a message into the void


This makes sense. There's that whole "half-closed" thing we used to deal with on the web side, if I remember correctly.

I think part of the problem may be that these sessions are stuck in the middle of a transaction, which is to say that the server is still either sending or expecting data, as opposed to sitting idle waiting for the next command.
Citadel Server binds a session to a thread while a command is in progress, and unbinds it when the command completes. Both the idle timer and the cancelled session reaper skip right past sessions that are bound to a thread.

If this is what's happening, then I need to totally re-evaluate how that works. The winning move might be to ignore the session state completely, look only for idle time, and instead of terminating them by setting them to be reaped, just perform that so_linger/close operation on the socket. This would theoretically cause the connection to reset and then it would get cleaned up by itself just as if the other end terminated the correct way.

I've added an extra parameter to the session listing code in the server.
Once this update makes it to the production system, the next time someone does this to the system I can look at the session listing and confirm that this is what's happening.

I can see how that might happen. On the other hand, my desktop is set up that way (SATA SSD main drive, HDD for backups) and there doesn't appear to be any impact. I wonder if it has anything to do with the fact that SATA still emulates the old primary/secondary setup of IDE, and ST-506 before that, and I have the drives on different controllers. Basically I have them as drives 1 and 3 instead of as drives 1 and 2.

If that is the case then I'll be sure to put the SSD's on 1 and 2, and the HDD's on 3 and 4.

Sounds like it was most of AT&T and some of Verizon and T-Mobile. That makes sense because carriers sometimes buy roaming capacity from each other.

Hey, sometimes it happens. I had the pleasure of visiting the headquarters of CenturyLink/Level3 just a short while after their nationwide outage (and got a sweetheart deal on some nationwide 100 Gbps capacity because they were still trying to recover from it at the time). Just for the asking, they showed me all of the different kinds of network management equipment they used, and pointed out which vendor's equipment had the cascading failure and why.

Anyone who works in technology knows that shit happens. As much fun as it is to immerse oneself in conspiracy theories -- indeed, I test them that way -- sometimes a network outage is just a network outage.

That having been said, I sincerely hope the big three cloud providers have catastrophic and permanent outages that they never recover from. They're all too big.

I have been around the block a few times too and seen ( and have ) my share of 'oops'. But this one just 'feels' wrong, cant fully explain but it does not seem like a normal SNAFU/Oops moment.

The balloon appearing during the outage ( and us not being told about it at first.. ) only made my suspicions worse.

They have been running new power lines in my area the last few weeks, though they were starting on my block this morning. But no, there is a 2nd fiber company also running lines... 

Just what we need, MORE lines on the poles...  And more lines to break when the trees fall from wind.

 

Back where i grew up it was all underground.

More fiber providers is better; it makes them compete for your business. I just wish they'd be more proactive about removing the fiber. I live on a street that connects the central office with a large number of subscribers at the other end and we have multiple giganto-trunks on the poles, probably thousands of copper pairs that are mostly derelict. Fiber is overlashed on those, making them difficult to remove.

Where I live we have long had a choice of getting Internet from "the phone company" or "the cable company" but both of them are running IP over fiber (PON) at this point.

The theory is nice, but the reality ( around here anyway ) is that prices are always about the same in the various markets, and always rising. Its sort of a wash what you choose, if you have more than one choice. ( like cable, you get ONE choice..  For local land line, ONE choice )

I'm not saying they are actively colluding, but i think there is an unwritten rule or something.

Interesting. That hasn't been my experience. My bill hasn't gone up in the 15 years I've had fiber. When I finally got them to drop the bundle and just give me Internet about five years ago, I've had 1 Gbps fiber service for $89.99 (including taxes and fees) ever since then. That's from Verizon ("the phone company"). Altice aka Optimum aka Cablevision ("the cable company") really wants my business and stuffs my mailbox with flyers several times a week.
Their current offer is $80.00 (not including taxes and fees) for 1 Gbps.

At the end of the day it's the same service: IP over PON on fiber. No voice, no video, just two companies competing to sell me a "dumb pipe". If either one tried to jack up their prices I'd switch to the other one, and they know it.

Eventually the idea of a provider being "the phone company" or "the cable company" will fade into obscurity now that voice and video are both being delivered over IP. I continue to believe that the PSTN should be shut down completely, like they are doing in the UK, and transformed exclusively into a virtual service running over IP.

As for television, most channels are just a toxic sewer main emptying into your living room, and I don't care what happens to it as long as it isn't in my house.

Ours constantly increases. Little by little..    After the tornado that leveled a big chunk of our town, it jumped like 20 bucks...

Everyone here complains. "its just like Comcast when they screwed us"

Even dumb pipes can be of different qualities. My second job operated on a SMB plan which included ISP provided equipment for the premises. The equipment wasn't abysmal bad, but if you had any issue with it you had to call Business Class Customer Support.

If you Americans think customer support from India sucks, just try to imagine what customer support does a crappy country get from its "India".

Eventually we moved from the provider to one that was about twice as expensive.

Actually I imagined a crappy country wouldn't have to outsource its tech support because local labor was already cheap.

The point is a crappy country might be crappy, among other things, because there is no way to hire anybody local XD

But then you also have to consider the biggest example: China. China is the World's China, but Africa is China's China.

Commercial television is a toxic sewer main emptying out into one's living room, but for those still stupid enough to pay for it, you now have one fewer choice.

[ https://tinyurl.com/7brsenau ]

"DirecTV is buying Dish and Sling as the company, a deal it has sought to complete for years as seeks to better compete against streaming services that have become dominant."

This leaves basically only one option for those who have no terrestrial cable or internet television service available. I don't consider it a loss of course because there's nothing worth watching.

Personally I think Directv/dish are missing a golden opportunity. The window is still open. We're starting to see smaller cable companies shutting down their television service entirely, and instead offering package deals that include YouTube TV. But why give all the money to Goolag?
Directv/dish ought to offer a "white label" OTT service that local and regional cable companies can rebrand as their own. They already have the broadcast centres built, they already have the carriage agreements in place, all they have to do is white label it and sell it to every cable provider. They could even sell set top boxes for subscribers who still want the traditional boob tube experience.
