Russian Credit Card Authorization Centre Reduces Downtime To Under 15 Minutes A Year

According to the press release, the system availability is about 99.997% (15 minutes max downtime per year). This sounds quite good from an availability point of view.

These are some of the benefits that the MACH11 technology offers in comparison to a traditional active/passive cluster.
