Excerpt:
One of the reasons the Fastly outage seems so wide scale is that cloud computing service companies like Fastly are consolidating, leaving websites dependent on a shrinking number of providers. Even if there aren’t that many total outages, the fact that so many everyday sites rely on fewer cloud providers makes each individual outage feel pretty significant to an average internet user who just wanted to buy some stuff on Amazon and read the New York Times early Tuesday morning.
There are benefits to consolidation, explains Doug Madory, the head of internet analysis at the network monitoring company Kentik. For instance, a smaller number of cloud providers means it’s much easier to get those providers to deploy a particular security change. “The flip side is the liability [of] having a few megacompanies, whether they’re CDNs or other types of internet firms, responsible for a lot of our internet activities,” Madory told Recode.
In other words, when one of these megacompanies updates its systems and inadvertently causes an outage, the damage radius could be quite wide. This is what happened in 2011 when one of Amazon’s cloud computing systems, Elastic Block Store (EBS), crashed and brought Reddit, Quora, and Foursquare offline. After the incident, Amazon explained that engineers inadvertently caused technical problems that trickled down through its systems and caused the outage.
