Curly Hair Annoys Rachel WIND

Only spit balling here, YMMV, but several observations I have after having the problem again. Chrome responds with the 504 error within about 40 seconds. Firefox (latest) responds with nothing, it waits for a response from the server for about 50 seconds then it just stops trying to do anything and stays on the current page. It seems to last for about 20-25 mins before the site loads again. While trace and ping, at the same time the site seems unresponsive, work, the bottleneck seems to be the final link to the server, (i.e. the server not responding to the remote client request quick enough). The server logs possibly have a bunch of similar errors in them but they should reveal more about the error, stuff like bad php requests, or page errors, etc.

Terrorizer - World Downfall

Warrior - System Thrashed

There goes my idea that it was mostly a middle of the day thing. Not even 8am and I spent about 25 mins not getting a response from the site.

XII Boar aren't too bad, but like a lot of bands these days they are very quiet. I don't think they've done anything since about 2017

Sabaton - The Great War

Yeah, same for me on both Firefox and Chrome. Delays with loading mostly and it seems to happen around the middle of the day here in Oz. I don't remember getting the bad gateway error recently, just delays.

I really like their latest at the moment. Before Humanicide came out, and maybe again soon it will go back to Ultra-violence. Diamond Head - The Coffin Train
