As far as we can tell, it was a worldwide issue.
Tesla experienced a massive network outage on Wednesday that left countless Tesla owners unable to connect to their cars through the mobile app or use the Tesla website, according to electrek. The outage appears to have been worldwide, with people around the globe reporting the same lack of functionality.
The issue is mostly a minor one, even though many Tesla owners use a cell phone as their key. In theory, the Tesla Model 3 and Model Y still ought to be accessible with the correct cell phone using Bluetooth - no network connection required - and the older Model S and Model X can use a mobile data connection to lock and unlock with only a phone present.
What's more, Tesla in it's owners manual recommends always carrying a key, even if you plan to use your phone to access the car, because cell phones have this pesky tendency of running out of battery life sometimes.
Still, features like Tesla's Smart Summon require communication with the Tesla network, rendering them out-of-commission in the event of an outage. More crucially, other Tesla products like its solar panels and Powerwall home battery systems were reportedly put out by the issue, as well, with owners not being able to monitor the devices.
As for the website, it was left completely unusable by the network outage, returning an error after the main page and leaving customers unable to configure vehicles or place orders.
Thankfully, owners began seeing functionality return as soon as half-an-hour after the network outage was first discovered. Still, it wasn't the best timing for a company that just saw its share value drop after CEO Elon Musk's Battery Day presentation failed to blow Wall Street's socks off.
The automaker used the Battery Day event to reveal its new, $145,000 Tesla Model S "Plaid" and announce plans for a future $25,000 EV after cutting battery costs in half. But as usual, the plans lacked specifics, and they referred to a car that is, according to Tesla, still roughly three years away, so there was little of substance.
