Datadog Synthetic Monitoring allows you to proactively monitor your applications so that you can detect, troubleshoot, and resolve any availability or performance issues before they impact your end users. With our API test suite, you can send simulated HTTP requests to your API endpoints, check the validity of SSL certificates, verify the performance and correctness of DNS resolutions, test TCP connections, and ping endpoints to detect server connectivity issues.

With the widespread use of LTE (Long Term Evolution), we are seeing more IoT devices come online in remote regions of our planet. Picture this scenario: A country is currently experiencing a national emergency due to an electrical grid failure. To mitigate the power shortage the government has deployed generators in the remote regions of their country to power the most remote villages. The problem? The villages are still reporting outages due to the emergency generators running out of fuel.

Websites are a must-have for any business that wants to survive in a highly competitive environment. Many people mistakenly think that only e-commerce projects need a website, but this is not the case. Absolutely every company needs website performance monitoring and virtually every initiative should be armed with its own webpage. But this article is not about why you need a website, but about how to track and manage its performance.

Observability is a measure of how well the internal state of a system can be inferred from its external outputs. It helps us understand what is happening in our application and troubleshoot problems when they arise. It’s an essential part of running production workloads and providing a reliable service that attracts and retains satisfied customers.

The rolling Comcast outage on Monday, November 8th and Tuesday, November 9th affected customers across the U.S., knocking users offline around the country. The first wave took place Monday evening in the San Francisco Bay area. The second, which had a wider geographic impact, occurred Tuesday morning, primarily affecting broad swathes of the Midwest, Southeast, and East Coast.

We're a small team of engineers right now, but each engineer has experience working at companies who invested heavily in observability. While we can't afford months of time dedicated to our tooling, we want to come as close as possible to what we know is good, while running as little as we can- ideally buying, not building. Even with these constraints, we've been surprised at just how good we've managed to get our setup.
