Major websites were unavailable on Tuesday due to an error with a content delivery network (CDN). An error in an update on Fastly Inc’s (NYSE:FSLY) content delivery network (CDN) saw some of the world’s biggest websites stop working for a period on Tuesday. Whilst techies worked to reset the error blank pages and ‘Error 503” messages were shown to visitors to the likes of Amazon.com, Reddit, CNN, Bloomberg, and the UK government’s website. Perhaps bizarrely, Fastly Inc’s shares are soaring in the wake of what was evidently an “all publicity is good publicity” moment in the spotlight.
