It's good for your house too. I've seen houses where the homeowner never ran their A/C and they were proud that they saved money. They also had problems with mold, paint peeling, drywall falling apart, and various wood things in their house warping.

At one place I lived, there were ceiling fans throughout the house, which was nice. There were also some on our back porch. The ones inside stayed in almost original condition. The ones outside had rust on the metal parts, and the blades warped.

But this was a discussion about datacenters, so I talked about the corrosion problems with IT equipment.

Well, both sides get charged. We're all either charged on capacity or 95th percentile throughput.

I've never known a residential provider to charge for used throuhgput, because people have a hard time understanding it. People would flip out if their bill was $20 one month, and $300 the next. Rather, residential providers do a bit of math. They look at their bill, the aggregate bandwidth used, and the total Mb/s available to customers. Of course, they tag on a nice profit. There are additional considerations, like what do they need to provide extra services like IPTV, how much does it cost to maintain existing circuits, add new circuits, keep employees paid, travel costs for technicians, etc, etc, etc...

So, you get a nice low flat rate, because consumers don't use 100% of their bandwidth 100% of the time. Basically, they oversubscribe. If they do it right, you never know. If they do it wrong, you have shitty service and everyone complains.

At the datacenter we have equipment, we pay for the rack, power, and on the 95th percentile utilization of that circuit. So if we idle everything for a month, we barely pay anything. If we dump all the load to that datacenter,

If you're running a business where you need to be in a datacenter, your business model better cover all your costs. Otherwise, you'll be out of business quick.

No one gets a free ride. You pay for your end-user line. I pay for the line my server is one. Everyone's paid, and everything works.

A lot of people who complain about government are people who would like to terminate most, if not all, labor protections. They bury that desire in ideological ruminations, and have convinced vast legions of rubes that the only good government is a non existent government, and somehow the magic of market forces will protect workers.

since there is no air conditioning, you don't have a condensation problem

No, it's not HVAC induced condensation. Meteorologists call it the dew point.

Right at this moment, the temp is 53.3F with a relative humidity of 78%. The dew point is 47F.

You're suppose to run a datacenter between 40% to 60% relative humidity. Without a system in place to dry the air, they're asking for corrosion on parts.

You can't say computers are corrosion proof either. When I worked in a computer store, we had computers come in all the time that were in houses with no HVAC, so they were exposed to outdoor humidity.

I left some old gear in a friends garage for a while. One of the units was a used Catalyst 5000, with cards I didn't really care about. When I put it in the garage, it was in functional condition.

I decided to bring it back up to play with. There was corrosion on the line card handles, and I'm sure corrosion inside. Nothing looked bright and clean. There was visible corrosion on the cat5 pins (for the cat5 ports). When I took it out, it barely worked with lots of errors. Reseating the cards didn't help at all. I don't know (or care) which parts went bad, I sent it off for electronic scrap recycling.

Someone's going to be really pissed off when they spent a fortune on servers that have to be trashed because they stop working properly.

There are other parts machines in the garage too. I only go to them for fans, power supplies, etc. I had already pulled out all the memory and CPUs. Sometimes they still work. Sometimes they don't.

Specs have some wild numbers on them. Some say they operate in 10% to 90% humidity. Sure, they *can* run in it for a while. They aren't expected to survive in that kind of temperature indefinitely. I've seen some specs that say they'll operate over 120F. Sure, for a very short time. I had one place argue with me because the spec showed wild numbers, but they were already experiencing hardware failures for operating servers in an uncooled server room (the HVAC broke, and they didn't want to fix it).

I agree completely. When I first started using an dreaded (an old LG keyboard phone with a JavaME spun reader I had hacked on to it) I found reading a bit of a chore. It took me a few days to get really comfortable with the seemingly small and yet ultimately pricing differences. Now I regularly read books on my smartphone and tablet without a hitch, and have noticed no recall problems.

There ought to be a law where any citizen can force a prosecutor to prosecute people that are suspect of committing a crime. Any prosecutor that gets too much cases where this law has to be effected should be subject of a research into his true loyalty. I wonder what party would dare to come up with a federal law to make this happen....

Did you look at their floorplan? There are huge wedge shaped gaps.

Or lets do math. For the sake of argument, lets say that the diagram in their virtual tour was to scale. We're also going to say that each rack is a standard 19" rack, taking up 22" each. That can be wrong, but it's what I'm using for measurement.

The entire circular structure has an area of 24,052 sq/ft.
A square structure on the same property would be 30,625 sq/ft
The circular structure wastes 6,573 sq/ft.

Each pod, with a 3' buffer on each end, and a 3' buffer between rows would have a footprint of 768.4 sq/ft. Since I only included one aisle buffer on each (since they share common aisle), add one more aisle at 102 sq/ft.

The total datacenter rack space is really 3,944 sq/ft.

In the difference between the round and square structure, you could put all the racks and aisles. and still have 26,681 sq/ft.

Or about the size of two Olympic size swimming pools.

Or 0.017 LoC.

Or 53,362 bread boxes one layer deep.

Or you could tile the floor of the wasted space with approximately 106,724 AOL CDs, which coincidentally is about half of the total number of AOL CDs received in Centennial, Colorado in one bulk mailing. Unfortunately, it will be very ugly, because you're trying to tile a square floor with round objects which has lots of wasted space.

I could dazzle you with more numbers, but you've already started cursing me, and I really don't care.

(really? Cogent? really really? Well done, Netflix. Not pinching any pennies, at all)

It seems most people either don't know about who's service is how good, or they ignore it.

But hey, they could have gone with Internap. Did they ever lay any of their own fiber, or are they still pushing traffic over the cheapest possible transit?

So?

I used to run a big adult site. We wanted servers closer to the customers for speed. We made enough that we didn't really care about the connection costs. We'd put up server farms around the world where it suited our customers best.

We owned every piece of equipment in our cabinet or cage (depending on the location). The provider equipment ended at the fiber they dropped to us, and the power outlets.

Netflix was hosted with Amazon for a while. A couple years ago, they claimed to have started their own CDN.

Their own CDN site talks about putting Netflix gear out for free. So they are basically saying they want the free ride. No one gets rack space, power, and connections for free. The right thing to do would be to lease the space like everyone else does.

But hey, they're loving to cry about being treated unfairly. They are the loudest ones about it. Honestly, other than speed complaints that are usually a fault, not a conspiracy, I don't know of anyone else talking about the same thing.

It is possible that the world is ganging up on Netflix. It happened to Cogent, more than once. That was mostly they refused to pay on their contractual obligations.

Disclosure: I'm a professional Penetration Tester

We find plenty of this sort of setups at our customers. Customers set up VPNs, have a password policy and a virus scanner. They have firewalls and keep user policies restricted. Then we come and we trojan someone, or find a weak WiFi password or whatever we use to get a foothold inside their network all it takes is one little mistake and we're "in". Once we get there, we log keyboards, get password hashes from network or system memory and start to pivot all over the place. Usually, our software will trigger virus alerts, but staff doesn't react to those "in a timely fashion" and we get to keep going even though alarms are going off on several computers. We could cloak our malware and sometimes we do, but usually it's too much trouble and we get domain admin passwords within a few days and rule the network in such a way that admins wouldn't be able to get rid of us if we would rootkit and backdoor properly.

It takes more than some policies and a VPN these days. You need IDS, proper procedures, layered security and skilled, motivated staff that knows how to deal with security incidents. You need properly trained and aware users that aren't afraid to admit they messed up and that have no problem reporting others doing wrong either. Don't trust on a single technical measure, but implement them all and make sure you test and train on a regular basis. Get a data classification policy and protect data according to that policy. That means that stuff like SSNs and anything that can be used for identity theft should get extra layers of protection and alerting implemented. If you don't do all this, a serious intruder will usually get what they want.

Please go away.
