Data Center Emergencies: How Critical are they for the Business?
Various data center (colo or corporate – it does not matter) malfunctions are always unpleasant. Downtime, dissatisfied customers, loss of reputation – this is just the tip of a huge mountain of potential problems that can be caused even by a minor malfunction of the IT infrastructure. Of course, a number of technical and organizational precautions are taken to prevent emergency situations. But one can't foresee everything. Thus, emergencies happen from time to time. Data on how critical data center malfunctions are for the business can vary considerably: figures vary by country, economy sector, company size, and other factors. Therefore, international statistics do not always correspond to our day-to-day realities. But still, how critical data center malfunctions are for domestic companies? We decided to get the answer by surveying the market participants themselves. We'd like to share the results with our readers.

Most of the incidents that are usually talked about happen in the «public» data centers. But there are a few data centers of this kind in our country – the vast majority of facilities is owned by the corporate customers or government agencies. It's not customary to discuss emergencies: in case of a data center owner it can lead to losing a positive corporate image, while in case of a contractor it will be a stain on the reputation. The analysis of failure causes would be a constructive way to improve the overall reliability of the local data centers making up this large market segment. The article gives some illustrations of practical experience, mainly - corrections of «someone else's» mistakes. The detailed info on facilities and incidents was modified, possible coincidences are accidental, but all the cause and effect relations are true to fact.
