Survey: Top Network Resiliency Concerns are ISP Problems and Hackers

Determining the cause of internet outages and unplanned website downtime often means looking no further than your business’ ISP, according to the results of a new network resiliency survey.

Oracle Dyn and O’Reilly Media surveyed 621 networking professionals across a wide variety of industries and company sizes and found that internet service provider (ISP) reliability issues were the top reason for internet disruptions and outages within the last 12 months.

But malicious hackers continue to play a major role in network resiliency problems as well. Spam and phishing-related attacks, denial of service (DoS) or distributed denial of service (DDoS) attacks, and web application attacks round out the list of top reasons for network disruptions over the last year, according to the survey.

Cloud strategies, cloud concerns

The vast majority of survey respondents — 74% — report that they are responsible for working in the cloud. The most common reason companies use the cloud is to run applications and services, followed by development and testing purposes. The cloud is also a popular choice for web hosting, storage, and backup and disaster recovery.

Despite the pervasiveness of cloud technologies, businesses still spend time worrying about the best ways to ensure reliability of cloud-based services and applications; controlling the cost and return on investment of cloud deployments; readiness to respond to cloud outages; and cloud providers’ attention to security.

Top mitigation strategies revealed

The survey also shed light on common strategies network administrators employ to defend against and mitigate outages. The most common steps administrators take to reduce the chances of an outage include firewall protection, site health monitoring and web traffic steering, and DDoS mitigation tools.

Companies that use cloud technologies also take steps to ensure the resilience of cloud deployments, such as load balancing across sites and clouds and using multiple failover sites. Just under 30% of respondents said they rely entirely on cloud provider to ensure resilience of cloud applications.

Key takeaways

The survey found that most organizations have experienced one or two network outages within the last year. ISP failures and cyberattacks are a major concern, and for the most part, companies choose to mitigate these problems through different forms of redundancy, such as over-provisioning resources and using multiple cloud providers and multiple DNS services.

But far too many organizations are relying on their cloud provider alone to ensure resiliency. These companies should take a closer look at their strategies and consider additional measures to ensure that web services remain up and running.

The companies that will be best prepared to prevent and deal with network resiliency issues in the future are those that make use of cloud-based web application security and traffic management tools such as web application firewalls, bot management, advanced traffic steering, and redundant DNS.
