If you had internet problems yesterday, you weren’t the only one. And this time, it wasn’t Ooredoo’s fault.

Major websites including Twitter, Reddit and Netflix went down temporarily on Friday after a company that provides core internet services for them was attacked.

US-based Dyn said it was subjected to a global distributed denial of service (DDoS) attack yesterday afternoon. The attacks continued well into the evening.

These types of hacks involve flooding target sites with “junk” traffic so that they can no longer serve legitimate visitors.

The move appeared to hit parts of the US the hardest, but also left Twitter, Whatsapp and some other services in Qatar on the fritz:

Dyn said it’s been working to resolve the issue and asked customers to check its status updates for more information.

Did you have any internet problems this weekend? Thoughts?
