F2Pool, the world’s second largest bitcoin mining pool, has been hit by large distributed denial-of-service(DDOS) attacks in recent days.

According to Mao Shixing, creator of F2Pool, the attacks first appeared on July 14.

“We are being DDoS’d in a hostile manner. Our technicians have been working on it all night. They swiftly updated the pool server to push the huge amount of networks that botnets request and deployed multiple defense mechanisms in light of attacks.”

A lot has been going on as we are moving closer to August 1. Could the DDOS threats have anything to do with F2Pool’s supporting SegWit2X?

On July 16 F2Pool announced that these were deliberate and vicious attempts to make the pool inaccessible.

“We have reported the incidents to Beijing Police and we have locked in on a number of suspects based on gathered evidence.”

F2Pool says that they are working with police to collect more evidence and make criminals pay.

As DDOS attacks continue to surge in number, F2Pool warns miners to alter DNS server addresses to 223.5.5.5 and 223.6.6.6, set up their miners to backup-eth.f2pool and backup-zec.f2pool.com:3357. The current etc mining address is still available in a short period, but they suggest miners switch to etc.f2pool.com:8118 and set up a backup pool to backup-etc.f2pool.com:8118.
