[citation][nom]theo4654[/nom]Ok ppl here is the bottom line to this! PS3 users have the right to complain about what is happening right now due to this so called attack!As a computer techy for the last 20 yrs. there is no reason not to protect your assets from attack..I see it everyday when I'm building or repairing computers. Sony is turning out to be another Microsoft! They claim there product is great, but can't handle the problems they create for themselves when they don't have a clue how to protect thier own hardware!I can see why these kids are angry, everyone kno's that Dev's make thier games now with DLC's, and not the old fashioned expansion packs of old! You have to be online to use these DLC's even when your offline single player! So I have a great concern that Sony is becoming another Microsoft, meaning which that they care about thier bottom line only, and that's $$$$$ not the true example of fine craftsmanship in hardware or software!!! And I don't need to hear that ohh it's free online use! It does not matter, you have a product to market, always make sure you have all the bases covered, before you sell that hardware...That's where now Sony and Microsoft do not care about quality control...it's only who can beat who to the market place first![/citation]
I had similar thoughts. And am also someone who has been in the tech industry for nearly 20 years. New/backup IPs. Changing DNS (if the attack is DNS-based). Round-robin DNS (spread the attack over several machines). Firewall exemptions at the service provider to discard packets from a block of IP addresses (blacklist/blackhole routing).
These are examples of ways to combat DDoS, assuming this is what is happening. The technology exists to "mitigate" the problem. Not eliminate, not prevent, but mitigate. The barrier is cost, not time. Sony has had plenty of time.
Testing: Has Sony tested their PSN infrastructure in a sandbox environment to see what the effects of a DDoS would be?
