Here&#x27;s the only page I could quickly find on Github&#x27;s architecture for those interested:<p><a href="https:&#x2F;&#x2F;github.com&#x2F;blog&#x2F;530-how-we-made-github-fast" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;blog&#x2F;530-how-we-made-github-fast</a><p>This looks like a single datacenter. I don&#x27;t see anything here indicating high availability or other datacenters. You&#x27;ll usually spot either an outright mention of it or certain components&#x2F;setups common in it. They might have updated their stuff for redundancy since then. However, if it&#x27;s same architecture, then the reason for the downtime might be intentional design where only a single datacenter has to go down.<p>Might be fine given how people apparently use the service. It&#x27;s just good to know that this is the case so users can factor that into how they use the product and have a way of working around the expected downtime if it&#x27;s critical to do so.
