I have to say it directly - I'm getting more and more convinced that highload and userload are the same people, and I'm sorry if I'm wrong, but these sites always start experiencing downtime or other problems at the same time. Now highload and embedo upload is completely dead and admin seems nowhere and suddenly userload/tubeload/redload all go down. Payments on both websites started taking forever when userload went down (now highload is little faster, but I don't think it was coincidence either).
If one disappears suddenly for some reason then I'm for sure also abandoning the other one too, and will replace all links.
And admin keeps promising stability but always more problems. I hope it will be fixed in several hours and not takes days. (if it gets fixed at all).
And highload and embedo upload problems have been happening forever and admin hasn't responded for long. Horrible negligence. I give admin some more time benefit of doubt, but then I will have no choice but to remove my files, replace links and never come back to these hosts again.
