I just don't understand how a large carrier such as Delta can get so much wrong. What's the DR plan? Are they using ASNs? A company is product, people, and computers. This is not the 20th century, flight plans aren't filed by telephone calls for these guys.
I've tested our DR plans and we were operational after 4.5hours, optimally. And we were 3 people.
This outage reeks of PHBs doing lots of kicking the can and not a whole of implementing.
- xjlin0 10y agoSounds like your DR plan or your network don't require power. Care to share?
- yardie 10y agoYes, 2 datacentres, Microsoft's DFS, cloud backups, and staff trained to know what to do. For the datacentre I have a friend that we worked out a mutually beneficial arrangement. I keep a few spare servers in his racks and he has a few in ours. Just enough to run the essentials. Testing was literally walking up to the rack and switching off the power. Then documenting what happens next. If you've configured the ASN just right the domain should roll right over to the backup servers. Offsite DR servers needed a little kick to bring up to speed (I can't remember why this wasn't fully automated). Most of the time was waiting for backup files to restore and verify. Since we were using someone else's network we were shaped down to a small percentage of their bandwidth. After that we had a debriefing to see what worked, what didn't work. The usual IT stuff.
