Or is geo-DNS returning the results intended?</li> <li>Is TLS certificate propagation for my CDN working as intended?</li> <li>Is one region significantly slower than another? Is my CDN caching working as expected?</li> <li>Are my geo-HTTP redirects working as intended? (For some interesting examples try <a href="http://www.yahoo.com" rel="noopener noreferrer">www.yahoo.com</a> and <a href="http://www.cnn.com" rel="noopener noreferrer">www.cnn.com</a> in non-US regions)</li> </ul> <p>There are many tools that exist that provide these answers, but nothing that answers all of these questions in one place.</p> <p>That's what RegionCheck aims to provide.</p> <p><strong>Who it's for</strong></p> <p>RegionCheck is designed for engineers who work with cloud infrastructure, including:</p> <ul> <li>DevOps engineers</li> <li>Site Reliability Engineers (SREs)</li> <li>Platform engineers</li> <li>Backend developers</li> <li>Anyone who likes to take a peek at backend infrastructure</li> </ul> <p><strong>Try it out</strong></p> <p>RegionCheck is available at <a href="https://regioncheck.io" rel="noopener noreferrer">https://regioncheck.io</a></p> <p>You can run free checks directly from the website; or create an account to access monitoring, alerting, the API, and additional features.</p> <p><strong>I'd love your feedback</strong></p> <p>RegionCheck is just getting started, and I'd really appreciate feedback from the engineering community.</p> cloud monitoring networking testing
