we’ve come up with Daniel Dib with a simple but powerful idea: to share our network-related horror stories with wider community, and then learn from the mistakes.
so – please treat this post as an invitation to share your network-related horror story with us. make sure to double-check if you can post information that you share (because, you know, our employers have sometimes interesting ideas about NDAs and other ‘secrets’). also, let us know if we can share your name/employer information or if you’d rather stay anonymous. as hard as it can be – try to finish with the ‘things I learned’, so others can learn and don’t make those mistakes in future.
After numerous CCDE bootcamp editions here in Poland, we’re together with Micronics starting the online CCDE bootcamp. today’s first day, covering design principles, CCDE exam best practices and get into the zone and “CCDE mindset”.
If You’d like to join us, please contact Micronics.
“For those who still don’t get it: if you lose the communication between cluster members (which would happen after DCI link failure), the firewalls in one data center shut down and cut that data center off the net.”
