Hackers briefly overwhelmed at least three of the 13 computers that help manage global computer traffic Tuesday in one of the most significant attacks against the Internet since 2002. Experts said the unusually powerful attacks lasted as long as 12 hours but passed largely unnoticed by most computer users, a testament to the resiliency of the Internet. Behind the scenes, computer scientists worldwide raced to cope with enormous volumes of data that threatened to saturate some of the Internet’s most vital pipelines.
This was quite a significant attack but didn’t really seem to effect much except the machines themselves. There doesn’t seem to be a motive, but three of these DNS root servers were specifically targeted. You can check out the graphs here and see just how much load both “G” and “I” had.
