The unplanned downtime this evening resulted from a Distributed Denial of Service attack on a large range of IP addresses. For those of you who are unfamiliar with DOS and DDOS attacks, you can find background information here:http://en.wikipedia.org/wiki/Denial-of-service_attack.
From our initial discovery, this attack was not intended for MemberClicks or a specific organization using the MemberClicks product. At this time, the product is up and running at full capacity and our in-house team is working in conjunction with our third-party data center team along with their security experts to further address this and other similar issues in the future.
To bring service back to normal and upgrade to a superior DOS prevention/mitigation service provider, our systems team made the difficult decision to update IP addresses across the system. While these changes won’t affect most of our customers, it’s important to note that many custom domains are currently not resolving to MC due to this change. To fix this issue, it is necessary to update the IP address for web traffic in your domain management console.
For those customers that have transferred domain ownership to MemberClicks, we have made the updates on your behalf and these sites are up and running as usual. Similarly, for those customers that have pointed to our name servers, no change is required.
For those customers that manage their own domains, you will need to update your DNS to point to a new IP address: 220.127.116.11
This should be a simple, straightforward change that involves removing the IP address you currently have stored in the A record value and replacing it with the new one we provide.
Most registrars/DNS providers should have a similar process. We've included step-by-step guides for the two most common registrars, GoDaddy and Network Solutions, below.

THE BELOW INFORMATION IS ONLY FOR THOSE CUSTOMERS WITH A CUSTOM DOMAIN AND POINTING AN A RECORD TO MEMBERCLICKS
To make the change:
- Log into your domain registrar/DNS provider's domain management interface. Once there, select the domain you use with your MemberClicks service.
- Navigate to the DNS Management section of your domain (this could also be called Advanced Settings/Options.)
- Navigate to your DNS Host Records.
- Locate the current A record that has the IP address 18.104.22.168 or 22.214.171.124 in the data field. Change that IP address to 126.96.36.199.
- Click Save.
Your A record should be properly saved although your changes will not be reflected immediately. The DNS record change will be reflected as soon as Internet Service Providers update their records.
