I'm not sure why it happens. Say I am using 4 of my private proxies... I set it running on one instance. It's going fine. I setup another instance and use those same proxies but as it starts it gives me 100% fail rate and the list runs through really fast. Like they don't 'take'. I have used these proxies before on like 4 instances in the past. It doesn't seem to be the proxies themselves that are bust cos they are still chugging along fine in the 1st instance. Also it doesn't seem to be related to a ban or anything like that cos I started the list again and now they are working. This has happeend a few times before and a few times more recently. So any ideas what causes it? I just started my second instance ok just now but it seems to have gone into this 'freewheel' mode and come to the end of the run. It's like SB doesn't get in gear and just revs with the clutch on to the end of the list. I started it again with the same proxies and they are working for now but dunno if they'll go again just as fast. So any ideas?
