Currently, the PFF server is under DDos attack causing it to be incredibly slow. I haven't been able to stop the attack yet but I'm working on it. My apologies for the inconvenience.

Distributed Denial of Service attack.

 
quote
A distributed denial-of-service (DDoS) attack is a malicious attempt to disrupt normal traffic of a targeted server, service or network by overwhelming the target or its surrounding infrastructure with a flood of Internet traffic.


So what I see happening is that all of a sudden, hundreds and hundreds of machines are simultaneously retrieving pages from PFF. Now PFF isn't hosted on some huge network of servers, but on a single server. It should be able to handle normal traffic just fine, but hundreds of requests simultaneously is a bit much for it. It will slow down to a halt and eventually crash. Fortunately I am able to restart the server remotely, even power cycle it remotely if needed. In the past I needed to make a 1.5 hour trip just to reset the server...

How does power cycling your server help things?

Aren't the requests coming from outside? If you reset your machine, how does that stop the excessive requests from coming in?

It doesn't (well, obviously if the server has crashed, power cycling makes it at least responsive again). But power resetting the server gives me about a minute to close all ports the requests are coming in to, giving the server some breathing air. I can then add some firewall rules that block most malicious access.

It was 20 a month last I checked. Not sure if the free version would work for the forum. I have the business package for my store(s) works very well.
