The DDOS was an entirely seperate issue, but resulted in pronounced packet loss and international slowdowns.
As for the optics: We were trying to isolate the fault over the weekend, but access to physical locations, fibre backhaul vendors, and equipment held us up until it was finally pinpointed and resolved this morning. It was also not a consistent issue, which made it hard to resolve.
Our network is pretty large, and complex, I can't exactly give you a diagram here on a public forum.
We do try and be as transparent as possible.
There was another DDOS attack this afternoon, but it was successfully mitigated. They happen all the time, but they don't always affect our network.
