Was the update automatic? Who approved the update? Who is managing the system?
I have a customer, with an entire IT group outsourced and internal to manage over 500 Windows 2012 R2 deployments using Cisco UCS, they consistently manage to fail.
Every application server/vm/ftp is unique and any update, reboot or change needs to be piloted before distributed to production servers.
People are lazy, full of excuses.
The thought of using Linux invokes that a REAL administrator is watching his underlings, kingdom and domain and will assure there is no shenanigans.
If any of you guys, girls, integrators, trunk slammers, hikua experts, distributors or avigilon fan babies have YOUR SOFTWARE set it and forget it deployment on AUTO.....You should be exposed and fired for being absolutely incompetent.
Instance 1: Customer does not like the failures on their system (Access Control, CCTV, PSIM, Integrations). So you go on site, tap the network and pen test the crap out of it.
Once your survey, report, analysis is completed you can totally exhaust the integrator excrement that original set the system up with basic understanding configurartions from a technician boot camp. Just another trunkslammer or even a LARGE corporation (with sub contractors) weaseling along until they get that project closure money. At that point it is the service departments job to fix and in comes the next round of DIY (ADT/CONVERGINT/STANLEY/JCI) noob techs to double charge for troubleshooting a system that was never commissioned in the first place, had no plan for system updates (OS and Software / Firmware).
Last, IF YOUR SYSTEM FLATLINES AFTER A WINDOWS UPDATE, ANTI-VIRUS UPDATE, FIRMWARE UPDATE....then you are not qualified on that hardware. Please stick to your b-connector splices, Tri-ed box sale, ADI hikua designs and GTFO the arena. Right now. Get to the choppa.
It seems those who cannot IT are at the bottom of the barrel bumping their gums on all the technological services they provide. Windows or Linux....know your game and stop shrugging your shoulders over system outages. KNOW YOUR GAME OR GTFO. YES YOU.
