These DDoS Attacks Are a Big Deal

We already pointed out that the Azure team stopped the largest known DDoS attack last November. That one originated from about 10,000 sources, from multiple countries, and it lasted about 15 minutes.

But it wasn’t the only significant attack. Microsoft says it also stopped three larger attempts in the second half.

In October, the group put the kibosh on a 2.4 Tbps DDoS attack. Then there was the 3.47 Tbps behemoth in November. Then came December, when the Azure team caught two more attacks — again, in Asia — that both surpassed 2.5 Tbps (one came in at 3.25 Tbps, the other at 2.54 Tbps). That attack lasted just more than 5 minutes.
