Microsoft reported recently that it had fended off a 2.4Tbps DDoS attack in August. The attack – launched from 70,000 sources in Asia and the US – was the second biggest attack on record, eclipsed only by the 2.5Tbps attack Google faced in 2017.
“The attack vector was a UDP reflection spanning more than 10 minutes with very short-lived bursts, each ramping up in seconds to terabit volumes,” the blog post saus. “In total, we monitored three main peaks, the first at 2.4 Tbps, the second at 0.55 Tbps, and the third at 1.7 Tbps.”
Microsoft claims their Azure DDoS protection service is capable of absorbing “tens of terabits of DDoS attacks”.

Oh hell ya. Let me attack myself and monitor myself. The results will always be the same.
I think azure is a good database service but I usually use the Amazon AWS.
So now we know why they won’t offer fiber to Americans.
