[SAC] [Hosting] Update on the NXDOMAIN DNS DDoS issues

We finished our deployment of dnsdist late last week and we had our first real test against the NXDOMAIN attack yesterday afternoon (3:30-6:07PM PST / 2330-0230 UTC). Thankfully it looks like dnsdist did its job and we did not have any noticeable issues during that time window! If you did notice an issue, please let us know by sending an email to support@osuosl.org. Or if you or noticing any issues since we’ve migrated to dnsdist in front of BIND.

Thank you to everyone who pointed us in the right direction with using dnsdist.
