I received the following email, addressed to me at an email address on my personal domain (for which I run my own mail server on a VPS):

Your network will be DDoS-ed starting 12:00 UTC on 08 May 2016 if you don't pay protection fee - 10 Bitcoins @
If you don't pay by 12:00 UTC on 08 May 2016, attack will start, yours service going down permanently price to stop will increase to 20 BTC and will go up 10 BTC for every day of attack.
This is not a joke.
Our attacks are extremely powerful - sometimes over 1 Tbps per second. And we pass CloudFlare and others remote protections! So, no cheap protection will help.
Prevent it all with just 10 BTC @
Do not reply, we will not read. Pay and we will know its you. AND YOU WILL NEVER AGAIN HEAR FROM US!
Bitcoin is anonymous, nobody will ever know you cooperated.
Obviously, I'm not going to pay the ransom. Should I do anything else?
I forwarded the email and original headers to the originating ISP. They replied that "Measures have been taken." So, umm, yay? I guess?
