Internet outage: Amazon, other major retailers still working

Amazon and other major online retailers' websites are still working amid this afternoon's massive internet outage, but they're taking their time to load.

The outage appears to be affecting dozens of online services, including the ecommerce platform Shopify. Walmart and Target rely on Shopify to support their third-party marketplace sellers.

Mashable reporters were able to add products to their cart and get through the checkout process on Amazon, Best Buy, Target, Walmart, and eBay as well as several online stores that use Shopify (Sennheiser, Good American, Allbirds, Brooklinen, and Netflix). However, all sites we tried were very slow to load.

It's still unclear what exactly caused today's outage.
