Only 36% of companies in the UK with an internet presence reckon their online performance is reliable, placing pressure on CIOs to deliver fast, more reliable services no matter where they are.

Only 52 out of the 100 IT decision makers quizzed by Dyn (unsurpisingly an Internet performance firm) monitor factors outside of their network which can affect performance, with 26 stating that they don’t have a back-up plan in place for their data centres if there is a natural disaster, outage, or delay.

"The Internet has become a major part of every business network and these companies must have insight and understanding of the entire landscape to ensure an exceptional end user experience," said Jeremy Hitchcock, CEO of Dyn.

"End users have never had higher standards and more options. Companies must rise to these expectations or risk missing out on the opportunities increased performance offers."

It’s retail companies, those that potentially have the widest audience, which are best at keeping tabs on their Internet reliability – obviously because their business models rely on online transactions. 56% of those surveyed by Dyn said that they monitor factors on the wider Internet that could affect performance. However, rather worryingly, less than half of financial firms which were quizzed said they did the same.
