I took like 3 years to my company to get this huge-ass client to ask us to remake their website (the client is already our client for other purposes).

The old website was hosted on their local machine, behind a proxy that was there for other 30 website servers.

The old website took like 30-40 seconds to load on a browser and had a google score of 3-6/100.

We made the new website in wordpress, since it was basically a blog and managed all of the older links to redirect to the new pages so that SEO wouldn't get affected.

We then asked the previous developers to let their domain redirect to the new one (it was like example.com => ex.example.com and now it's just example.com, so we needed them to make ex.example.com redirect to example.com).

What they did was making a redirection to the 404 page of the new website, making everything go to fuck itself.

Damn this might be the first time I despise other developers, but this move was fucking awful.

I mean, I get it, we stole your big client, but it's not our fault if we made the google score go up to 90/100 in a week just by changing server and CMS.
