Infrastructure operators are struggling to cut back the speed of IT outages regardless of enhancing know-how and robust funding on this space.
The Uptime Institute’s 2022 Outage Analysis Report says that progress towards decreasing downtime has been blended. Investment in cloud applied sciences and distributed resiliency has helped to cut back the influence of site-level failures, for instance, however has additionally added complexity. A rising variety of incidents are being attributed to community, software program or methods points due to this intricacy.
The authors make it clear that vital IT methods are way more dependable than they as soon as have been, because of many many years of enchancment. However, knowledge protecting 2021 and 2022 signifies that unscheduled downtime is continuous at a price that isn’t considerably diminished from earlier years.
Most organizations – 80 p.c – have skilled an outage up to now three years, with about one in 5 of these surveyed saying that they had a critical or extreme outage throughout the identical timeframe.
“Serious” and “severe” are the highest two scores within the Uptime Institute’s five-level class rating for outages. “Serious” covers disruption of providers with doable monetary losses or compliance breaches, whereas “severe” covers main and damaging disruption of providers with probably massive monetary losses.
Based on the information it has collected, the Uptime Institute report suggests that every yr there’ll seemingly be at the very least 20 critical IT outages the world over that trigger main monetary loss, enterprise and buyer disruption, and reputational loss.
When it comes the reason for outages, the report notes that, in addition to a main trigger, most produce other components that additionally contribute to an incident. Power failures are listed as the most typical outage trigger, with 43 p.c of them itemizing this as the first issue, adopted by software program, community, and cooling all accounting for about 14 p.c of incidents.
In the Uptime Institute’s annual resiliency survey – one of many knowledge sources for the Outage Analysis Report – community points have been listed as the most typical reason for all end-to-end IT service outages usually, with power-related points coming second.
The Uptime Institute additionally discovered that third-party industrial operators reminiscent of cloud, internet hosting and colocation suppliers accounted for nearly 63 p.c of all public outages over a five-year interval, and this share has crept up yr by yr to 71 p.c throughout 2021.
However, the important thing phrases listed below are “public outage,” and the report authors notice that the reliability of public cloud providers has come underneath larger scrutiny in recent times because of some high-profile outages, in addition to the rising curiosity in operating vital providers within the public cloud.
Nevertheless, the survey discovered that enterprise IT managers are “somewhat concerned” in regards to the resiliency of public cloud providers, with solely 13 p.c of respondents saying public cloud providers are dependable sufficient to run all their workloads, and the variety of “don’t know” responses has elevated since final yr.
Drilling deeper into the causes, the Uptime Institute discovered that UPS failures are the most typical motive for power-related outages adopted by turbines, switch switches, and energy distribution items.
The commonest causes behind a network-related outage are a tie between configuration/change administration errors and a third-party community supplier failure. These are usually not stunning in trendy community environments, the report states, the place networks are continuously being up to date to optimize efficiency or meet new necessities.
Another pattern reported by the Uptime Institute is that the period of outages additionally seems to be growing, at the very least for publicly reported outages. This is worrying as a result of an outage is prone to be extra pricey and disruptive the longer it lasts.
In 2021, the variety of publicly reported outages lasting longer than 48 hours was 16 p.c, in contrast with 4 p.c in 2017, whereas these lasting between 24 and 48 hours stood at 12 p.c, in contrast with 4 p.c in 2017.
The price of outages has additionally risen. In 2019, 60 p.c of main failures are estimated to have price lower than $100,000, whereas 28 p.c price between $100,000 and $1 million. In 2021, solely 39 p.c price lower than $100,000, whereas 47 p.c have been between $100,000 and $1 million. The proportion of outages costing over $1 million grew from 11 p.c to fifteen p.c.
The knowledge feeding into the Outage Analysis Report comes from 4 fundamental knowledge sources, in line with the Uptime Institute. One of those is a public outages database it maintains, one other is a confidential system for members to report irregular incidents, and the opposite two are its Global Survey of IT and Data Center Managers and Data Center Resiliency Survey. ®
