Knowledge heart outages are on the decline, and funding in on-site backup techniques is the principle motive. That is the one-line takeaway from the newest Uptime Institute study of data center outages.
Hold studying for a deeper dive into knowledge heart outage tendencies this yr, in addition to an evaluation of what they imply for knowledge heart resilience and restoration planning.
Key Knowledge Middle Outage Traits
The important thing findings from the Uptime report embody the next:
-
The entire variety of outages per facility has decreased in comparison with earlier Uptime Institute stories. (In absolute numbers, outages have elevated, however that is as a result of there are extra knowledge facilities than there have been prior to now.)
-
Fifty-five p.c of organizations reported having skilled a knowledge heart outage prior to now three years.
-
Nevertheless, solely 27% of organizations that skilled an outage recognized it as “important, “critical” or “extreme.”
-
Because of this general, fewer than 15% of companies have been topic to a notable outage throughout the previous three years.
-
The failure of energy and cooling techniques was the commonest trigger of information heart outages, accounting for about 71percentt of all outages.
-
Human errors contributed to about half of notable knowledge heart outages, with failure by workers to observe procedures topping the listing of kinds of human errors related to this development.
-
Cyberattacks have been negligible as a trigger of information heart outages, accounting for a mere 1% of all such occasions. (It is essential to notice that the examine examined the causes of outages affecting knowledge heart amenities as a complete, not disruptions to particular person workloads. If it had performed the latter, cyberattacks would most likely have factored in far more prominently.)

Why Knowledge Middle Outages are Declining
The primary motive why knowledge heart outages are declining in frequency, in response to the Uptime analysis, is that corporations have invested in redundancy techniques for his or her amenities. Multiple-third of respondents reported having elevated energy and cooling system redundancy.
The Uptime Institute cites this knowledge to counsel that constructing redundancy into every knowledge heart – versus developing a number of knowledge facilities and distributing workloads throughout them – is one of the best ways to enhance general uptime. It says this development flies within the face of “expectations that multi-site approaches will undermine costly, bodily web site redundancy methods.”
That stated, a statistician (which I’m not, though I as soon as took an “Introduction to Statistics” course in faculty) would possibly take problem with the implication {that a} correlation between greater charges of system redundancy and decrease outage frequencies interprets to causation. It isn’t truly crystal-clear that that is the case, and the Uptime analysis would not elaborate on this level.
Nor does it element how investments in multi-site methods have modified lately. It is believable that the common variety of websites has additionally elevated, which might be a think about decrease outage charges.
Nonetheless, the indisputable fact is that extra corporations are investing in redundancy, and there may be at the very least a correlative relationship between this development and decreased outages.
Methods for Decreasing Knowledge Middle Outages
On the entire, the report means that the next are profitable methods for growing knowledge heart availability and lowering the chance of outages as of 2024:
-
Put money into redundant energy and cooling techniques (protecting in thoughts the caveats mentioned within the previous part).
-
Deploy superior resiliency options, reminiscent of software program that mechanically strikes community visitors and workloads throughout an outage. Uptime says this strategy “can cut back outage dangers and their related influence over time,” though it notes that there could also be a short lived enhance in outages as a result of it’d take time for corporations to be taught the intricacies of the brand new software program.
-
Do not give attention to cybersecurity as a key technique for stopping knowledge heart outages. Defending particular person workloads is actually essential, however the knowledge reveals that cyberattacks very hardly ever trigger whole knowledge facilities to fail.
-
Put money into coaching for knowledge heart technicians, and/or automate processes utilizing autonomous instruments, to scale back the chance of outages brought on by human error.
Conclusion
No single survey of information heart outage tendencies can reveal every thing that companies ought to do to extend uptime. However the Uptime Institute’s knowledge is among the many most up-to-date and detailed data obtainable about what appears to trigger outages and the way corporations can cut back their dangers, and the takeaways are clear: General outage charges are declining, plausibly due to elevated funding in redundancy – though human error stays a serious risk.
