Quickly Switching Your Servers to Backups?
moogoogaipan writes "After a few days thinking about the quickest way to bring my website back to the internet users, I am still stuck at DNS. From experience, even if I set the TTL for my DNS zone file as low as 5 minutes, there are still DNS servers out there won't update until a few days later (Yeah. I'm looking at you, AOL). Here is my situation. Say that I have my web servers and database servers at a remote backup location, ready to serve. If we get hit by an earthquake at our main location, what can I do in a few hours to get everyone to go to our backup location?"
You could hire an actual IT administrator who knows what they're doing? Like, one who's actually trained?
Depending on the industry, that's a very real problem.
Sysadmin: "Don't worry, we're already switched over to the hot spare, just get out of there!"
CIO: "What if the whole building goes?"
Sysadmin: "No worries. Remember that $1M we spent stringing all that fiber over to the other datacenter?"
CIO: "Oh yeah, the one in WTC 2!"
Sysadmin: "Aaw, shit."
That was me... sorry... my bad. FSB's (Fiber Seeking Backhoe) are tough to control.
