Some Google services were temporarily unreachable for some users due to internet traffic being misdirected; Google believes cause was external, will investigate
Internet giant says issue has been resolved and it will conduct an investigation — Google services were temporarily unreachable …
Context & Ripple Effects
The 2018 incident fits a pattern the related coverage keeps confirming: when Google breaks, it breaks across many products at once. A major Google Cloud outage in June 2019 took down YouTube, Snapchat, Gmail, and Discord for hours, and in December 2020 a botched account-authentication update produced a worldwide hour-long outage of Gmail, YouTube, and Docs.
What distinguishes this earlier event is the stated cause: Google attributed the misdirection of internet traffic to something external rather than its own systems, meaning part of the failure path sat outside its direct control. That framing matters because Google's own post-mortems in later incidents traced failures to internal changes instead.
First-order effects
- Users and businesses depending on Google's bundled services lost access to several products simultaneously, since shared infrastructure turns one fault into a multi-service outage.
- Google committed to investigating an external cause, putting the reliability question partly on third-party network operators whose routing decisions it does not control.
Second-order effects
- Each recurrence — the 2019 Cloud outage, the 2020 authentication failure — gives enterprise customers of Google Workspace and Cloud fresh evidence for diversifying across Microsoft and Amazon, making reliability a competitive selling point for rivals.
- Because the cause was external traffic misdirection, network operators and transit providers face pressure to tighten route filtering, since their mistakes propagate directly into consumer-facing outages.
Third-order effects
- If the pattern holds, Google's breadth becomes its structural vulnerability: any shared-layer fault — routing, authentication, cloud control planes — cascades across the whole product portfolio, pushing regulators and large buyers to treat single-provider dependency as a systemic risk rather than a Google problem.
The trend: Google's recurring multi-service outages, from external traffic misdirection to internal authentication errors, are turning hyperscale service concentration into a standing reliability and dependency debate.
