All the company's name servers were offline at one point
Cloud-based DNS provider Zerigo has been hit by a distributed denial-of-service (DDOS) attack. According to the company’s network status page, the cyberattack started on Friday, June 21, at around 15:00 UTC.On Saturday, at 3:37 UTC, the company reported that all their name servers had gone offline.
“We are currently experiencing a DDoS attacks against Zerigo DNS services. It has escalated and has now affected b.ns.zerigo.net and d.ns.zerigo.net as well now,” Zerigo noted.
Currently, B and D name servers are back online, but others are still offline.
In early June, at least three other DNS providers reported being hit by DDOS attacks. The systems of DNSimple, easyDNS and TTP Wholesale were abused for a DNS amplification attack against another network.
It’s uncertain if the attacks are related to the one currently experienced by Zerigo, but hopefully we’ll find out soon.
