What are the risks associated with legacy data centres?

Posted by Volta Newsroom on 02-Feb-2017 10:00:00

A significant amount of data centres in London were built in the 1990s and early 2000s; a large number of these legacy sites need to go through major overhauls, potentially exposing their customers to more risks of power outages and more disruption. Customers of these legacy sites are also more at risk of power outages, as the recent data centre failures in London have demonstrated. What are the dangers associated with legacy sites, and how do they affect customers?

It is likely that data centres built in the 1990s and 2000s will go through large overhaul processes in the coming years. The larger the overhaul that is needed to take place, the higher the risk of disruption for their customers’ business.

Careful planning is required to effectively manage the extensive maintenance required during a large overhaul. Furthermore, the data centre must have dedicated staff to look after the maintenance before, during and after the overhaul. If this is not effectively implemented at every stage, then their customers’ data may be inaccessible, causing detrimental effects to their business.

If disruptions occur, customers will have to liaise with their end customers in order to communicate the potential disruption. This is likely to damage their brand and also upset the relationship with their end customers.


Organisations who are invested in older data centres will be more at risk of suffering outages due to outdated equipment which will be overloaded with the data deluge the new world is bringing. In 2016 in London, 100% of colocation data centre failures were from sites built more than 15 years ago.

These power failures have had expensive consequences with many customers being affected and with some power outages lasting up to 10 hours. Some of the reasons for the data centre outages included UPS failure and high voltage drop. According to the 451 Research Market Insight on 2016 Data Centre Failures, “failures are likely to be noticed. Most data centres house many clients and systems. Failures will quickly be noticed and social networking will ensure that competitors and press are alerted.”

Organisations using legacy data centres should assess the risks of staying with older data centres. Moving to a more modern colocation provider such as Volta Data Centres could save them from the stress of going through major overhauls or the cost of suffering from a power outage.
