I'm having the same problem, can't connect with chrome, IE, firefox and the tapatalk app
I can connect through a VPN or by using mobile data on my phone
Edit: looks like i'm able to connect again, oh wait it's going on and off
Can connect on phone, cannot connect on home network. Connection on home network to only two plus two had been shifty lately, requiring me to restart my wifi connection every few clicks lately. No other site gave me that problem.
Tried tracert on home pc with wired connection to wifi router, cannot resolve target system name. Same results for twoplustwo.com with or without forumserver. preceding.
We are monitoring a connectivity issue impacting our DNS environment that began at approximately 01:10 CST December 22nd. Our engineers have taken steps to mitigate impact from this issue, however some of our customers may continue to experience intermittent periods of latency, packet loss, or connectivity failures when attempting to reach rackspace.com or subdomains within rackspace.com. This may also continue to impact customer DNS resolution during this time. Our engineers are engaged and continuing work to stabilize the environment.
Thank you for your continued patience as we work to resolve this issue. If you have any further questions or concerns, please contact a member of your support team.
****UPDATE 22 December 11:15 CST****
On December 21st, at approximately 23:54 CST, backbone engineers identified a UDP DDoS attack targeting the DNS servers in our IAD, ORD, and LON data centers. As a result of this issue, authoritative DNS resolution for any new request to the DNS servers began to fail in the affected data centers. In order to stabilize the issue, our teams placed the impacted DNS infrastructure behind mitigation services. This service is designed to protect our infrastructure, however, due to the nature of the event, a portion of legitimate traffic to our DNS infrastructure may be inadvertently blocked. Our teams are actively working to mitigate the attack and provide service stability.
Thank you for your continued patience. We will provide updates as information becomes available.
