Add me to the list of low-ish UIDs saying thank you for creating what was once the absolute center of my Internet experience.

Over the years, /. has kept me informed, entertained, aware, and enlightened. While it hasn't always been the smoothest of sailing, I keep coming back.

Thank you, Rob. Thank you so very, very much.

Have you ever worked in a real environment?

There is ALWAYS a difference between test and production. No matter how many test cases and iterations of changes that you go through, there is always a non-zero percent chance that the change in production will behave differently.
This is why most companies require fall-back procedures for any production change in addition to testing.
It sounds like it may have taken them longer than some might be comfortable to reach the point where they did roll back changes...but I'm sure that this change tested as okay in all of their test cases.

"The Cloud" has always been nothing more than marketing buzz. All "The Cloud" is are physical servers running a hypervisor and running your machine instances as VMs.
There's still people, switches, routers, firewalls, servers, and storage that are used to build "The Cloud."

This belief that doing things in "The Cloud" makes them impervious to hardware failure, power outage, network connection drops, etc. has always been misinformed.

My company used a X4500 and we discovered the bug that caused Sun to make the X4540 - the Marvell SATA chipset in the X4500 had a serious bug in firmware that was exacerbated by the Solaris X86 Marvell chipset driver.
Under heavy small block random IO intermingled with heavy sequential large block IO, the box would kernel panic and hang - only a power cycle would reset the box.

Sun ended up refunding us the cost of the servers and providing us exceptionally large incentives to purchase Sun StorageTek storage.

It wouldn't surprise me if the X4540 would have similar issues because they were rushing to replace the X4500 to try and minimize the possibility about bad PR over the X4500 being amazingly unstable.

This is why I'll be waiting for FreeBSD to support this because they will probably have better SATA chipset drivers and the chances of the system hanging because the Solaris kernel drivers for the SATA chipset (nevermind that it's a SATA chipset that Sun put into their own board).
