On June 12 around 18:00 UTC, Google Cloud’s backend infrastructure failed globally. Authentication services went down. DNS broke. Data handling ground to a halt. Cloudflare Workers KV — also hosted on GCP — subsequently collapsed, creating cascading failures across the internet. Spotify, Discord, Google Meet, and countless other services went dark. The degradation lasted over 2.5 hours in some regions.
For most people, this meant a frustrating evening without their favorite apps. But for EV drivers who depend on cloud-connected chargers, it meant something far more consequential: they couldn’t charge their cars.
The Vulnerability No One Talks About
Most Charge Point Management Systems (CPMS) depend on constant backend connectivity. The charger needs to talk to the cloud to authenticate the user, authorize the session, and process the transaction. If your backend is unreachable, your chargers become useless boxes of plastic and copper.
During the outage, drivers couldn’t access apps or use RFID cards to initiate charging. The chargers were physically fine — power was flowing, hardware was operational — but the software layer that controlled access was completely dependent on servers that were thousands of miles away and offline.
This isn’t a theoretical risk. It’s a structural vulnerability baked into the architecture of nearly every EV charging network on the planet.
Why This Matters More Than You Think
Cloud outages aren’t rare events. Major cloud providers experience significant disruptions multiple times per year. And these are just the headline-making incidents — smaller, regional outages happen constantly.
Now layer on the connectivity challenges that already plague EV charging:
- Underground parking garages with no cellular signal
- Rural charging stations with unreliable broadband
- Construction sites and temporary installations with no fixed internet
- Multi-dwelling units where running ethernet to each charger is prohibitively expensive
The cloud dependency doesn’t just create a single point of failure — it creates a single point of failure in environments where connectivity is already unreliable.
The Offline-First Alternative
At HeyCharge, we built SecureCharge with a fundamentally different assumption: the internet will not always be there, and charging must work anyway.
Our offline-first architecture means:
- Authentication happens locally via Bluetooth between the driver’s smartphone and the charger
- Session management runs on-device — no round-trip to a cloud server needed
- Data syncs asynchronously when connectivity is available, using store-and-forward
The result: when Google Cloud goes down, when cellular networks fail, when the WiFi router in the parking garage reboots — HeyCharge chargers keep working. Every single time.
The Lesson
The central question isn’t whether cloud outages will happen again — they will. The question is whether your charging infrastructure is designed to survive them.
Charging infrastructure should prioritize fundamental functionality — allowing users to charge their vehicles — over cloud-dependent features like real-time dashboards and dynamic pricing. Those features are valuable, but they’re not essential in the moment a driver needs to plug in.
The day the cloud fell was a reminder that the internet is a convenience, not a guarantee. EV charging infrastructure needs to be built accordingly.
