Over a period of almost 20 hours people may have noticed Geekzone was sometimes slow to respond, not responding at all or just spitting out 500 errors (Server error).

 

Our database server was running at 100% most of this period. After investigating we found a couple of queries that could be optimised but this was not the actual root cause. Further investigation revealed a very large number of page requests coming from China - sometimes at more than 150 - 200 per second. Our poor little server couldn't cope with the stress at a times.

 

At around 6pm I implemented a whole country block, preventing requests originating from China to reach our server. I had to block the whole country because the requests were coming from different networks.

 

With this block in place the server was able to return to normal operation. At the end of the 24 hour period we had about 3.8 million requests, with 2.6 million coming from China alone.

 

The block remains in place, regardless of @sbiddle plans to visit the country in the near future.

When you mentioned performance, the first thing that came into my head was a song and dance by the moderators.... I blame this on too many kids plays and show attended recently 😂

Geekzone Stars?

 

Can't be worse than Block Stars. Or can it?

I'm guessing that anyone legitimately wanting to visit geekzone from China would be using a VPN anyway, to get around the various firewall issues. That would neatly skirt around the geoblock, would it not?

Correct. My guess this was an intentional DDoS, seeing the traffic wasn't really coming with a legit bot crawler browser user-string.

When I had to look after a website a while back (NZ based site that would be no use to anyone overseas) I found we were getting clobbered and used some tools to see where traffic was coming from.

 

It was actually pretty scary seeing relentless attempts to access the admin backend from all over the world - notably at the time somewhere in the former Soviet union was featuring pretty heavily.

 

You have my sympathy and respect!

Interesting. My guess, this thread is related:

 

https://www.geekzone.co.nz/forums.asp?forumid=48&topicid=250964

 

And in the first post of that thread, "Time to get Geekzone blocked in the PRC" wasn't the response.

 

GZ isn't accessible from China - but "403 - Forbidden" as expected from your block - but it seems as if the site's not firewalled by China.

 

 

 

At a guess, if the Chinese dictators want to launch DDOS attacks against political targets but deny direct involvement, they wouldn't firewall the target to block the botnet they claim they have nothing to do with. (don't shoot me if I'm wrong - I'm no IT expert).

Do we have conversations going on about the Hong Kong situation?

 

That's really disturbing behaviour eh.

Given most of those hits are cache hits, maybe there i still some optimization to make?

I was actually thinking it was 8chan taking revenge on Cloudflare.

Actually the cache hits are images and scripts. Pages are always fresh.

From what I've seen, nothing more aggressive (to PRC) than you'd read on any NZ or other western news site.

If this was indeed a DDoS I have my suspicions but talking about HK was not in the radar.

Missleading graph is missleading then..

 

 

 

Time for a server upgrade! we have to take on our new forum members clearly rather than block them! ;)

 

 

 

On a more serous note, thanks for getting to the bottom of this.
