A day in the life of Datacenter Disasters

Open Query currently hosts a large part of our infrastructure at Linode. We are extremely happy with their performance, stability and support. Unfortunately any chain is only as strong as it’s weakest link.

Quest for Resilience: Multi-DC Masters

This is a Request for Input. Dual MySQL masters with MMM in a single datacentre are in common use, and other setups like DRBD and of course VM/SAN based failover solutions are conceptually straightforward also.

After a good day of hitchhiking (weather is beautiful here) I stayed with my Pakistani Couchsurfing host and we had an extremely interesting evening talking about the gigantic cultural differences between western civilization and Pakistani civilization. It beats staying in a hotel by about a […]
