Critical infrastructure — including systems vital to energy, water, transportation, communication, healthcare, finance, the military, and more — is the backbone of any nation’s public health, safety, security, and economic stability. As a result of their necessity, these systems are prime targets for sophisticated state-sponsored threat actors, organized cybercrime groups, and even hacktivists interested in drawing the most attention to their cause.

As we navigate through 2025, Site Reliability Engineers face unprecedented challenges in maintaining system reliability and performance at scale. With the rapid evolution of distributed systems, containerization, and AI-driven operations, SREs need more sophisticated tools than ever to successfully do their job as serving as grid guardians.

To truly safeguard your infrastructure, it’s crucial to adopt a holistic strategy that covers every aspect of your network’s health and performance. This means integrating fault monitoring, performance monitoring, and availability monitoring into a comprehensive strategy. Lets discuss how a well-rounded approach to network monitoring can help you maintain resilience, optimize performance, and prevent downtime.

Numerous technological advancements have made it easier to conduct financial transactions and business. However, cyber-attacks and network inefficiency remain a threat. That’s why your business needs continuous network monitoring. Keeping constant watch over the IT infrastructure of your business is crucial for its survival. It would be very disappointing for your thriving enterprise to come crashing down due to easily thwarted threats that went unnoticed.

Alert fatigue is the silent productivity killer in IT operations, and its impact is more significant than you might think. A 2023 survey by CloudHealth Technologies found that 63% of organizations deal with over 1,000 cloud infrastructure alerts every single day. 22% report receiving more than 10,000 alerts each day. This highlights the critical need to minimize alert fatigue.

Behavior-Driven Development (BDD) is a software development methodology in which applications are built to match the behaviors a user would expect from the software. An evolution of Test-Driven Development (TDD), BDD gathers user stories about how users expect applications to behave, then creates software tests to validate that their applications match this behavior. The BDD methodology utilizes specific language and naming conventions.

Half of all server failures lead to staff working overtime, driving up costs and highlighting the critical need for effective monitoring. This underscores the importance of choosing the right network monitoring tool. It is a critical decision that impacts not only how well your infrastructure performs today but also how easily it can scale and adapt in the future. A comprehensive monitoring solution needs to balance deep technical capabilities with ease of use and scalability.

As modern networks evolve into intricate ecosystems spanning on-premises, cloud, and hybrid environments, the need for a robust, scalable monitoring solution has never been greater. Organizations face the challenge of maintaining performance, minimizing downtime, and managing ever-increasing complexity.

In 2022, we wrote about our engineering interview process to make it more transparent and accessible to candidates. A lot has changed since then: we've grown to 80 people across London, San Francisco, and New York, and naturally, our interview process has evolved too. We thought it was time for an update!

Backups are a critical part of any IT operation. You never know when a file may be corrupted or accidentally deleted, when a hard drive will suddenly fail, or a system will die. Backups help us recover from such incidents and provide peace of mind. However, something that is often overlooked is the practice of testing your backups, especially full system or image backups.
