Rate Limiting is now available to all customers across all plans as an optional paid feature. The first 10,000 qualifying requests are free, which allows customers to start using Continue reading

Worth Reading: Building Venice

What we do with Venice is support incremental upgrades of the cluster. Both of these approaches use a cluster of storage nodes.

Doing this one node at a time with each storage node in the cluster lets us do a zero-downtime upgrade. —LinkedIn

Unpatched vulnerability exposes Magento online shops to hacking

An unpatched vulnerability in the Magento e-commerce platform could allow hackers to upload and execute malicious code on web servers that host online shops.The flaw was discovered by researchers from security consultancy DefenseCode and is located in a feature that retrieves preview images for videos hosted on Vimeo. Such videos can be added to product listings in Magento.The DefenseCode researchers determined that if the image URL points to a different file, for example a PHP script, Magento will download the file in order to validate it. If the file is not an image, the platform will return a "Disallowed file type" error, but won't actually remove it from the server.To read this article in full or to leave a comment, please click here
