One of the sites on MATRIX server is currently under DDOS attack. We are working to identify the targeted site and mitigate this issue. iWe hope to resolve this issue as soon as possible. Sorry for the inconvenience caused. Please keep an eye on this blog post for further updates.
** UPDATE #1 **
Server is now up. We are closely monitoring for any more DDOS activities.
** UPDATE #2 **
We have now identified the site which was actually targeted for DDOS attack. We have now isolated it from this server. As a result, the server is now fully online.
IMPORTANT: We had to move all the sites to a different IP address because the original IP was getting a HUGE flood of DDOS attacks. The new IP may take some time to propagate and after that your site will be online again. Sorry for the inconvenience caused.
