A bunch of media and government sites were offline earlier today following an issue with the Fastly edge cloud platform.

Fastly operates a major content delivery network (CDN), which uses the principles of edge computing to run a bunch of geographically distributed datacenters designed to serve digital content more quickly. Regardless it looks like much of the world was affected some obscure technical issue, albeit for just an hour or two.

On the surface this is no big drama. Technical hitches happen and Fastly seems to have got to the bottom of it fairly quickly. But the scale of the outage provides another reminder both of how fragile our digital infrastructure is and how little redundancy is built into it. The sites that went offline as a result of the Fastly issue seem to have been entirely dependent on one provider for their entire online presence.

This isn’t the first time a public cloud provider has conspired to bring attention to the perils of putting all your eggs into someone else’s basket. Earlier this year AWS unilaterally suspended service to social media site Parler for largely arbitrary reasons that seemed to have more to do with political tribalism than anything else. Now even the UK government was unable to digitally serve its own population for some time.

Barely a day goes by without some cyber incident or other reminding us how exposed we are and yet there’s little sign of redundancy and effective fail safes being build into the digital world. Quite the contrary, in fact, with the current trend being for companies to entrust their entire infrastructure and computing capability to one of a few mega public cloud providers. What if AWS is hit by a similar problem?
