502 Bad Gateway

What....the fuck......is up?

Database access is completely screwed. I can't even switch between pages now!

Yeah, was getting this intermittently a lot earlier, but it's slowed down now. 

2 days now

almost goxlike

It hasn't slowed up for me. I'm still getting it sporadically. It is usually revolved around posting or refreshing a page.

BTW: I've written this post twice now and it's damn annoying.

Three times cut and paste to answer.

Four times.

Five times....ok this is pissing me off now.

I have also been getting a lot of those posting errors and report to administration pages.

for fucks' sake

Come on

What others said. Has been bad for past 2-3 days, but db error frequency has been particularly severe today. Have been surprised to not see a notice up on Reddit page.

I changed some things. Hopefully it's improved now.

It seems much improved. Thanks

Much better
Wish we could afford xeround mysql

Yup, fine for me now.

I got a error few minutes ago.

I got this error also just a few minutes ago.

Just happened to me again. Growing pains?

Currently 80% of requests end in a 502 error

server melting load volumes I am sure

502 Bad Gateway

Again today.

Wanted to say the same.

None of this here.

The forum 502s roughly 17 minutes before the launch of a highly popular coin. DDoS? Or just people clocking refresh every 15 seconds?

Honestly, I wouldn't mind a read-only cloudflare-based proxy as long as there's no chance to post or login there.

I've also had problems resulting in 80-90% requests ending up with a 502 error.

Been having a lot of problems the past hour or so. Couldn't even get on to the website for about 30 mins. 



 What coin is that?

I'm curious as to whether it is a DDoS or growing pains as well. I have noticed at times that Cryptsy and BitcoinTalk have been down simultaneously though I'm not sure which would explain that occurence -- clearly either could :(

Same for me. Every other page gives me 502 error. I can barely even post! I doubt I will even be able to post this.  :-\

Website seems to be running a little faster now. Fewer errors and faster response times. When I initially was having problems the server response was: 3800.01 ms it's now at 1063.78 ms. Which is a dramatic improvement.

Yep. The post that I made above was my first actual post that went through.

So this in addition to the broke-ass image proxy? Nice...

Seems to be picking up a bit now. Wonder if it was a ddos or just a lot of users logging on (or at least trying to).

Most likely ddos'ers

Sites been running pretty slow for me the past few hours and a lor of 502 errors again.

Yep, started again for me too.

Same. Probably all the media interest from the Coinye West coin  :D.

See this fellow a lot today.

502 Bad Gateway

In fact, as I posted that post I saw it.
So meta.

Maybe 502 Bad Gateway is the new name of the forum. Is there a new coin called "Bad Gateway"?

Forum is growing rapidly with 31,775 new members in December and 65,132,393 page views per month so depends if admin is investing in HW upgrade to cope, seems not.

I would think there must be a way to cache some of the content to cope better with all the page refreshes everyone does.

Still getting the error a lot...

So many 502s
It's getting worse and worse

Yes it is. Every other page gives me a 502. I guess if we wait it will go away.

Gar. 502 error ate my top post, and it took five minutes to navigate here to complain. Another DDoS?

This is what happened when they were attacked before, not much we can do on our end since it's just a forum, I'm getting it too.

I guess it had something to do with this:

Seems to be running a lot better right now either way.  :)

What is "THIS FEATURE"?

Ignore coloring.

Coloring the word "ignore" with a darker color when a user is ignored by many people.

I dont see how such a small error can make such a big difference.

I was getting it with a 50% frequency a few days ago. I am still getting it today, but not as much as before.

If the feature was written as:
-For every thread page of 20 posts that someone views:
 -for every user that posted:
  -look through every other user's ignore list and add up the times that user has been ignored

it certainly could cause server load. If it comes back, it would probably not be a "live" statistic, but one that is compiled nightly per-user.

FYI: Clicking a quote title will take you to the appropriate thread where the post was quoted from (quotes can be edited so this may not always run true)

Ahhhh, that helps a lot. Thanks.

That totally makes sense. Why add this feature if it was soooo resource intensive?

I don't think it was actually that bad back in 2012 (resource wise) but as the forum has grown such a huge amount since then it's just been getting slower and slower, have a look through the stats on here https://bitcointalk.org/index.php?action=stats

Didint even know this page existed. 65.1 million views last month!!!

That's basically how it works because the ignore mod (which I didn't write) stupidly stores ignore info in a single column per user like "35,3,...". So each ignore button needs to scan through all established users. The cost of this used to be very little, but it has increased substantially as the number of users has increased. I added a lot of caching long ago to offset this, but the cost is too high now even for that. I need to mostly rewrite the ignore mod so it stores data more sanely. No too difficult, but it requires a somewhat large uninterrupted block of time, which I don't have right now.
