Bitcointalk running slow/crashing (split from What happened to bitcointalk.org today?)

[ForceField]

Having another issue right now.

Is it yet another DDOS?

Probably DDOS combined with newcomers coming here to rant about the price falling momentarily.

Just been offline for ~5 minutes, and 500 Internal Server Errors are bombing all over the place.

Good god.  This site can't get any more unusable right now.

[demonmaestro]

its running for me. kinda slow but running....

[celkaris]

running really slow from here too, any page takes ages to load (30seconds to 1min+)

[Mike Christ]

I think the DDoS let up.  It's going okay for me now.

Yup butter smooth.

I think that it is legitimate traffic, but there is a ridiculous amount of it: ~250 requests per second. I made several changes to speed up the forum, which seems to have helped.

Some changes you may notice:
- The users online list at the bottom of the board index is gone. That was too expensive.
- Searching is now subject to the same spam protection limits as posting. So newbies have to wait 6 minutes between searches and users with more posts have to wait progressively less time.
- If you request pages faster than once per second too many times, your IP will be temporarily banned.

I wrote my own caching system because I didn't want to use memcached, etc. There may be bugs with this. In the future I may need to add more aggressive caching.

Thanks theymos! Bitcoin is on the front page of reddit along with various other sites, probably legitimate traffic.

Regarding searching, maybe you could point people to "site:bitcointalk.org search terms" on Google when they are being throttled?

The forum's search offers additional features that Google can't replicate.

There's a feature that makes it annoyingly difficult to refine a search: if you perform a search and don't find what you're looking for, your only option to proceed is to use the back button in the browser which resets all the fields to their default values.

Can you PM me the exact logic of this, so that I can ensure my scraper doesn't get banned.

Instead of having all the users, could we just have a ticker showing the amount of online users? I really like that info, think its kinda cool.

If not, could you tell us the max that was online, I heard it was 7,500! If so that is amazing.

From what I've seen of your bugs, they're better than some peoples' programs. Thanks for your efforts, t.

The max number of online users isn't being tracked anymore.

Thanks.
