Forum:Site slow/down?

I tried accessing the wiki earlier today and it timed out with a generic Curse message saying that the servers were overloaded, but no other Curse pages or wikis were experiencing the same thing. Currently, I can access the site but it is very slow (around 20 seconds per page load). Any idea what's going on? DoS attack? Bot going crazy? --(talk 22:03, 28 January 2012 (UTC)
 * Yes, there have been on and off problems all day yesterday. Curse tech people have assured me that it's not anything on the server side - they tried rolling back the recent code deploy, and all scripts have been finished. Looks like the cause is something changing on the content side within the last 12 hours - perhaps it's something within the new skin? It might be best to see if reverting to the previous skin at least temporarily might help when the problem reoccurs. Ausir 06:38, 29 January 2012 (UTC)
 * The last changes to the skin were made 32 hours ago (at the time I'm writing this). The only possible effect the skin could have on server performance is that a lot of people have to download the new CSS and images; otherwise the skin's CSS and JS have exactly 0 bearing on server performance since they're completely executed client-side. And if the server cannot handle many people at once downloading the new CSS, well, rolling the skin back will not solve the problem because then the people who had already downloaded the new CSS will have to re-download the old version.


 * Otherwise, there have been little to no changes on the content side yesterday which could have caused this. There were no changes to templates or anything else which could trigger large-scale server activity. The only change which could have had any possible effect (a minor change to MediaWiki:Common.css) was made after the trouble had already started.


 * And to be honest, this is hardly the first time the server becomes unresponsive for periods of time on the weekends. It happens fairly regularly. -- Porter21 (talk) 09:01, 29 January 2012 (UTC)


 * Here is something for you to ponder, I cant access the wiki as the page times out on my normal internet connection. Yet, when I use a proxy the site reacts perfectly fine and pages load without problem. User avatar tag.gif Avatar talk.png 09:58, 29 January 2012 (UTC)


 * Not the slightest problem for me at all... κηδεμόνας  [~μιλώ~]  13:23, 29 January 2012 (UTC)


 * I can tell you for sure that the issue is defiantly Curse side, after flushing my entire system - cache (including DNS cache), history, internet files etc. and trying different browsers etc., I was unable to connect and always timed out. It was sporadic for the first few hours, slow to connect or sometimes just didn't connect with the generic Curse message HunterZ got, then just down for good with the generic browser message since last night. I then tried a test (via http://www.downforeveryoneorjustme.com/) to determine if the site was responsive. It was, which lead me to 2 things, either my ISP was blocking the site or the site was blacklisting my IP. Since then, I tried a proxy (for which I left the above message with) and it connected fine, tried other curse sites - which it blocked me on all the wiki sites, but allowed the normal Curse sites to load. Finally, I have reset my network MAC address and IP address - an IP address I have had for the past few years =( - and now it connects fine. So the issue is with Curse blacklisting my IP and nothing more. From the symptoms I experienced - first a slow response to requests, followed by the site just not acknowledging any connection or requests, I would assume that the server has listed the IP as a DoS attack. Something I can see happening for myself, since I was using my bot prior to all this (doing null edits to cure some of the problems). But I have no idea why it would react the same for HunterZ, this defiantly needs to be checked into as it could be blocking other innocent parties from accessing The Vault, there is nothing worse than false positives which block visitors to our site.

 * Interesting. I definitely haven't done anything that could be considered spamming/flooding the site; I think the craziest thing I've ever done here is lined up edits on 3-4 related pages at the same time, then pulled the trigger on all of them at once - and that wasn't recently.
 * It's also odd that it said that it was the Curse back-end servers that were overloaded, and that the Curse admins were aware of the problem; doesn't this imply that the system should have sent some kind of alert email to the Curse admins about the issue? It's also weird that I saw two different, non-overlapping failure modes: the error message at first, then long page loads later. At any rate, it seems to have cleared up overnight. --HunterZ_tiny.png(talk 18:42, 29 January 2012 (UTC)
