For the past week I’ve either been up very late, or very early and have made a few posts between 4am-8am GMT and have noticed that during this time the Unity forum slows to a crawl. It mainly appears to affect making posts or editing posts and occasionally results in a ‘504 gateway timed out’ error.
Its quite frsutrating to have to wait upwards of a minute to have a post go through. Does the forum do any house-keeping between these times or is there some other explanation? Can anything be done about it?
Funny, I was just thinking about that. Yes, I believe it’s doing some housekeeping…this was an issue before, and they fixed it (by adding more hardware?) but given how it’s been behaving recently, I think it needs fixing again (add moar hardware!).
Edit: this post when through immediately though, so that’s something.
I have that trouble with various site slowness and timeouts but I know it’s because my cable modem firewall is configured with all types of precautions such that even a ‘busy-body’ web page with lots of objects will cause a false ‘syn attack’ to be registered by the modem as the TCP/IP streams are setup. Modem just isn’t fast enough with the extra firewall filter code running on a cable size stream bandwidth.
I don’t think it is related to modems, firewalls your ISP or anything like that as viewing threads doesn’t seem to be affected much, posting, replying and editing up until a few minutes ago (including my OP in this thread ) are what is affected.
Perhaps the house-keeping stopped at 5.30 am GMT, as since my OP (which did take a good minute before giving a 504 error) posts are going through normally again.
At that time most of servers have the crons scheduled to run. Some of those crons might involve the database (doing statistics) and hence the slow server.
If that is for your home connection you should take it out. It doesnt really make sense to use that type of protection for home, unless you are hosting some very high traffic websites (wich is also very unlikely). An attacker is not going to focus on your IP to block it just for fun.
