I've come to the realization that 503 errors are better than the current wave of 500 errors for a few reasons:

1. 503s are usually immediate and don't take 5 mins to load only to tell you that you have been pwn3d.
2. You can just have 503s reload.
3. While posting of you get a 500 error there is no way to know if the post went through or not leading to many double posts, with a 503 it means it did NOT go through.
4. You have to email the Admins every time you get a 500 and tell them what you did, the error message says so. 503s are less time consuming and tedious.
5. People complained more about the 503s, they don't seem to mind the 500s meaning they won't likely be fixed

Could it be related to usage?

I have no problem on my home computer, but at work, it's terrible.

Yeah! Down with the 500s!Ditto, but there shouldn't be any errors anywhere. You don't hear people complaining that at work they get 500s when they try to access Google or Amazon.
