Esk 🐌⚡💜<p>howdy, <a href="https://hachyderm.io/tags/hachyderm" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>hachyderm</span></a>!</p><p>over the last week or so, we've been preparing to move hachy's <a href="https://hachyderm.io/tags/DNS" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>DNS</span></a> zones from <a href="https://hachyderm.io/tags/AWS" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>AWS</span></a> route 53 to bunny DNS.</p><p>since this could be a pretty scary thing -- going from one geo-DNS provider to another -- we want to make sure *before* we move that records are resolving in a reasonable way across the globe.</p><p>to help us to do this, we've started a small, lightweight tool that we can deploy to a provider like bunny's magic containers to quickly get DNS resolution info from multiple geographic regions quickly. we then write this data to a backend S3 bucket, at which point we can use a tool like <a href="https://hachyderm.io/tags/duckdb" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>duckdb</span></a> to analyze the results and find records we need to tweak to improve performance. all *before* we make the change.</p><p>then, after we've flipped the switch and while DNS is propagating -- :blobfoxscared: -- we can watch in real-time as different servers begin flipping over to the new provider.</p><p>we named the tool hachyboop and it's available publicly --&gt; <a href="https://github.com/hachyderm/hachyboop" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="">github.com/hachyderm/hachyboop</span><span class="invisible"></span></a></p><p>please keep in mind that it's early in the booper's life, and there's a lot we can do, including cleaning up my hacky code. :blobfoxlaughsweat: </p><p>attached is an example of a quick run across 17 regions for a few minutes. the data is spread across multiple files but duckdb makes it quite easy for us to query everything like it's one table.</p><p><a href="https://hachyderm.io/tags/sre" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>sre</span></a> <a href="https://hachyderm.io/tags/devops" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>devops</span></a> <a href="https://hachyderm.io/tags/mastodon" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>mastodon</span></a> <a href="https://hachyderm.io/tags/infrastructure" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>infrastructure</span></a></p>
