Just what we needed. At this stage Silver Stackers is subject to an ongoing Chinese Bittorrent DOS attack. Basically a Chinese ISP trying to block torrents by DNS spoofing the trackers with a random IP address - and someone has decided that Silver Stackers was due to receive a bazillion unwanted requests to stop the locals from watching downloads of Fifty Shades of Grey. Mitigation efforts are underway, however this is likely to be a sustained attack for a while. Additional mitigation support has been sought from our hosts. The sheer volume of requests has compounded the existing performance issues the site was under (that were due to be worked on today), however activities on fixing general performance have been put on hold by the DOS attack response. More information will be provided as it is available. For now however I've been able to restore service, and I fully expect that the site will continue to be up and down for the next few days until the DOS is fully mitigated. https://www.facebook.com/SilverStackers is hosting status updates when the site is down (I just noticed the Facebook link in the head is out-of-date).
