[outages] AS 209 transit issues, maybe in IAH only?

Anybody else out there peer with AS 209 - CenturyLink / Qwest in the Houston area having issues with transit into your AS from 209? We've been having issues since Thursday 02/16/2017. Symptoms include (all from the perspective of our customers) some websites not reachable, DNS not resolving, email not being delivered. As soon as we installed filters to drop all advertising and receiving routes from AS 209, every issue was resolved. Our connection to CenturyLink has been up for years without any config change on our side. Tech support at CenturyLink has been a huge challenge. We understand CenturyLink had some sort of maintenance event on Thursday, but details are not fully understood. -ben
