proxy error when checking PR

@Sven: I have PRE checking the PR of my lists that PI identifies right now
200k URLs to check but after 1000 or so URLs checked it seems that the PRE Log shows mostly Invalid Server Error 500 and so returns an emulated PR of -1 as seen here: http://cl.ly/1n3S0f1X2e1K

I use the TF/10 rule and I use 74 private proxies

Any idea what we can do about that or what the reason could be?

Update: The message actually says: No valid result (500 Internal Server Error).
PI is set to only 50 threads.

How many proxies do you have and did you test them already?

Sammy262

See above: All 74 semi-dedicated proxies have been checked prior to use of course.

Sven

So I guess the proxies are banned by Majestic already? Can you check proxies against a custom URL like...
