Hosting Matters DOS Attack Continues

As many of you are aware sites hosted at Hosting Matters have been victimized by a massive denial of service attack targeted at one specific site: Internet Haganah.

Even though HM has been deligently working with their network providers to resolve this there have been several outages including one this morning which begain shortly after 9:00 AM and has extended to 3:08 PM this afternoon.

Note: this is not something I blame HM for in any way. I work at an institution that has had specific users targeted by denial of service attacks and they can be brutal and massive.

On the other hand, I am somewhat surprised that HM's upstream networks have failed to successfully block this traffic before it hit's HM's circuits. In cases where a single IP is targeted (which we are told is the case here) dropping traffic to this IP by the upstream provider(s) should always work so something is broken here.
