NASA Loses Contact With Space Station Over Software Update 111
kodiaktau writes "Reports early Tuesday morning say that a software update to the International Space Station caused a communications blackout with Houston control. Remediation of the update has allowed the astronauts limited communication every 90 minutes or so. It is expected that the issue will be resolved today."

That limit is because of how long it takes for a minimum sized packet to traverse the network for collision detection. If you can guarantee there won't be collisions (a switch does this) then you're pretty much not limited by length anymore other than signal strength. All you need is a bunch of switches to boost the signal up and you're golden.

That's a different, and probably more appropriate definition of "offshore". That also sounds like a very good procedure. I would have added "we only upgrade firmware to solve specific problems and vulnerabilities appropriate to our environment, not just because it's 'the latest'". But I'm told I'm too conservative.
Here, the admins are offshore (as in, physically on the other side of the world) but the machines are still local. They've rebadged former mainframe operators to be "hands and eyes" in case a button has to be pushed or a memory stick changed out. Of course, "hands and eyes" have had no hardware training whatsoever. I made some fuss recently when I caught one of them changing out a memory stick with the gator clip on their wrist strap dangling in the air. The response was to raise the issue as to why I still had access to the computer room? Geh.

There are ways to handle computer components safely without a grounding strap. For instance, putting bare forearms against the chassis frame when removing or inserting components.
One could argue that the ground strap is there to insure that you are always statically grounded even if you forget, or don't know about, other precautionary measures. I'd like to posit that someone with absolutely no hardware training probably doesn't know to touch the chassis before handling components, but apparently this also

Its 2013... any reason you're not using virtualization for these sort of things?

Right, but there is a huge space between "being cautious about updates" and "never installing and update". System updates, and most especially firmware updates need to be staged just like any application update. You apply them to non-critical systems first, test, and then cautiously apply them to up the line to your most critical system. Even then, you have to watch your application support matrix.

Software Verification and Validation (Score:5, Interesting)
I spent over 20 years of my career (now retired) working for a company that did independent verification and validation (IV&V) of software used by the military to operate its unmanned space satellites. Not once was a satellite lost from an error in the software if we were involved.
There were some 10 or more other, unrelated companies developing software for various space satellites. We did more than merely test the resulting products. We started by reviewing the developers' design documents; our reviews required responses or revisions before any coding could occur. Next we reviewed the developers' programming documents; our reviews required responses or revisions before programming could be completed. Then we reviewed the developers' test documents; our reviews required responses or revisions before the developers could conduct their own internal unit tests. We attended the conduct of those internal tests and audited the results to ensure that the purposes and criteria of the tests were satisfied.
Finally, the developers would deliver their software to us. We would test the products at the package and system level. We looked at how products from different developers interfaced with each other, whether human interfaces were reasonable, and whether the government's requirements had been met. Our test documents were reviewed by the military organizations that would be using the software, and we did not start testing until we responded or revised our test documents.
This IV&V process approximately doubled the cost of providing software. However, no such software caused a satellite to land on the White House or (worse) on the Kremlin. In the early 1990s, the Pentagon decided to save money by eliminating IV&V. I continued testing software for military satellites, but then it was within the companies that developed the software. When schedules or costs were at risk, testing was cut short.
