So I just got this report from 2 other users (on facebook) who I dont even know and then confirmed it myself, seems like someone ddos'd the server database ?
I was getting the 502 bad gateway error and the other guys were getting something like this :
Same here. This is the message that I got:
Migration testing ended up running an import script on the server ended up taking up way too much resources on the server. We are figuring out a better way to not starve the production box. This wasn't because of a DDOS.
Makes sense. It's not a DDoS since a site that's being attacked by a DDoS attack would either not display at all (and you might see a browser-generated error message instead of the site) or load very, very slowly.
As an aside, this is why HashProfit's claim of being forced to shut down temporarily because of a DDoS attack was very suspicious. The site itself was working perfectly fine even while the supposed DDoS was happening. Only the message displayed was changed.
EDIT: I didn't realize that the whole site went down with a 502 Bad Gateway error after the above message was shown. I left before it happened so I wasn't around to see it. Now we know it wasn't a real DDoS but that's pretty much what a real DDoS looks like.
