My ISP is your customer and you appear to be incorrectly applying strict reverse path filtering on their BGP managed link. If that's accurate, congratulations: you broke the Internet. Or at least the part of it encompassing 199.33.224.0/23. Please contact me so we can figure this out. Regards, Bill Herrin -- For hire. https://bill.herrin.us/resume/
