Its services - and those of its customers - came back online shortly after it was disabled. Its post put paid to early speculation that the internet had succumbed to a colossal hack, but parallels were drawn with last year's outage from its CDN-rival Cloudflare. Around 20 data centres went offline around the world, prompting a major outage in European cities after misconfiguration of a single Cloudflare router caused a massive data pile up. Gav Winter, the boss of Rapid Spike, the website performance and cyber security firm, says the Fastly outage was just another example of "how brittle the internet can be". "CDN's provide huge performance benefits, but they are run by humans, and humans can make mistakes as we've seen with Cloudflare recently," he adds.
