Some of you have noticed the site becomes unreachable with 502 error for short period of time recently
At first I thought it was amount of traffic hitting pass above allocated resources which in some cases can be a good thing, after upping those settings, it helped for a short period of time and problem comes back
The issue is when the site is having 502, my other sites that are running on the same server is completely running fine
Quick glance at the server stat monitoring I noticed some spikes on bandwidth during those time
My guess is we are experiencing spam attack that triggered by having a lot of files that we host (for example high number of requests to the screenshot thread at once )
Potential fixes are placing some restriction (I don't like to restrict users) on resources allowed to upload and better spam filter (which will be added when we move to new system )
