I've seen 3 Gbit/s attacks to minor sites for no apparent reason. I can't imagine what MTGox gets on a regular basis.

They say reading enriches the imagination.

Very high spikes. While baseline remained for the entire duration in the 5-10 Gbit range, I've seen spikes as high as 100Gbit and I'm not even sure I've actually measured the highest ones.

Re, the UDP suggestion. That might not be a bad idea at first glance. It'd work if MTGox advertised the price from some mostly unknown IPs and out different routers, out to a list of subscribers. Another option would be to put this data in DNS, maybe in a TXT or SRV record with a TTL of 60. Then the DNS servers might be attacked, which could be a new problem.

You are rubbing sticks together trying to solve already solved problems. The many ways available for talking to MPEx.
