Drivers and riders rely on Uber to get work or a ride at the push of a button. So last week’s outages—which intermittently affected over one million riders and 450,000 drivers globally over a couple of hours—was a significant miss.

We’ve fixed the problem but wanted to take this opportunity to apologize to our customers for the inconvenience caused. For drivers who couldn’t use the app, we’ve put money directly into their accounts to make up for the lost time and earnings. For riders, we’re offering discounts on their next two trips.

We’ve also worked hard to understand exactly what went wrong with our systems and to ensure that it doesn’t happen again. Because when it comes to work and travel, reliability is king.
