Why not? Things break. Electricity is one of those magical things that&#x27;s very hard to have insanely good uptime -- frankly, it&#x27;s incredibly impressive that power outages aren&#x27;t more common.<p>And why would GitHub not disclose that it was a DDoS? They were very forthcoming when there actually _was_ a Chinese DDoS last April: <a href="http:&#x2F;&#x2F;arstechnica.com&#x2F;security&#x2F;2015&#x2F;04&#x2F;ddos-attacks-that-crippled-github-linked-to-great-firewall-of-china&#x2F;" rel="nofollow">http:&#x2F;&#x2F;arstechnica.com&#x2F;security&#x2F;2015&#x2F;04&#x2F;ddos-attacks-that-cr...</a><p>And in a DDoS, the service typically becomes slower and slower until it reaches the point where only like one in a hundred requests succeeds. With the GitHub outage, it died fairly instantaneously, and it was completely 100% dead. There was no timeout as the servers tried to respond -- the &quot;no servers are available&quot; error page loaded instantly every time.
