I recall ARIN had a DDoS attack a week or so ago. Does anybody know if this is a recurrence?

Yes, it is.  I attach Mark’s notice about it from this afternoon.

Starting at 3:55 PM EDT on Friday, 25 March, a DDoS attack began against ARIN. This was and continues to be a 
sustained attack against our provisioning services, email, and website. We initiated our DDoS mitigation plan and are 
in the process of mitigating various types of attack traffic patterns. All our other public-facing services (Whois, 
Whois-RWS, RDAP, DNS, IRR, and RPKI repository services) are not affected by this attack and are operating normally.

We will announce an all clear 24 hours after the attacks have stopped.

Mark Kosters
Chief Technology Officer
