A multi-gigabit DDoS attack was directed at one of our customers on the Premium network. Our providers are now blocking the offending traffic upstream and connectivity should be fully restored. Please let us know if you encounter any further issues.
TW Telecom does have the ability to do null routing through community strings, and we have been doing it with them for 2 years. They are the only 1Gbps link we have anywhere in our network and it was supposed to be upgraded some time ago. Last I heard they are upgrading to 10G this week. This issue should not have been an issue, but it was on new IPs that were not added to the Arbor Peakflow SP which cause it to take more time to identify the specific IPs being targeted. That was fixed the night of the attack. Also, once TWT is upgraded to 10G it won't be an issue.
In addition we are adding more providers now that we have 80 waves up between us and Equinix.
