“After looking into this, it seems you have a hit song on your site,” the email from Netlify customer support reads. “Maan Bou Jan Sang Lou by Teresa Tang. I was not aware of her, but she seems to be a popular Taiwanese singer. This song is 99% of your bandwidth usage over the past 30 days.”

The letter further explained that a lot of bandwidth was generated from user agents that “are quite ancient using Google Cloud addresses”.

“This would include devices such as circa 2010 iPads, Windows 98 & Windows 6 computers. So either you have a fanbase with a passion for older technology, or this was likely a DDoS attack. To me, this seems to be the latter,” the email continued and suggested hosting such files on third-party platforms, such as YouTube or SoundCloud.

After explaining the standard practice of reducing the bill to 20% after such attacks, which would be $20,900 in this case, the Netlify support team offered a better deal.

“I’ve currently reduced it to about 5%, which is $5,225. I know this is still a lot of money, and I apologize for the inconvenience. If you like, I can raise this internally to see what else can be done.”

The user wasn’t happy with that and decided not to pay but post their story on Reddit and Hacker News instead.
