  Hello, We experienced a DDoS attack on our DNS servers last evening that may have caused issues with our DNS and hosted products. Our dev team was able to mitigate the attack and domains should be resolving at this time. If you continue to experience DNS resolution issues, please write us back and we will look into any potential further issues.
