I have been having the same issues as PurSpyk!!. Mine is just on Usenet at the exact same times between 19:00 and 22:00. Outside of those time it runs at full speed. Between those times it crawls to a halt. Even Afrihost's own news server is basically dead in that time
As per Dianysis comment regarding shaping, there should be no throttling, shaping or monthly thresholds on Business Uncapped packages. That is not the case. Checking via other ISP account and downloads flies.
I have also sent traces etc to Afrihost and everything has been sent to the network teams. But, then everything is slinet after that. Not a word from Afrihost unless I complain again. This is exactly the same symptoms that occurred last year before the big FUBAR.
My question is previous months my download ratios was very low. This month is was extremely high after a loss of a hard drive and a redownloading games, patches etc. To me it seems that because of this, there is a monthly threshold rule being applies by throttling services between times.
This cannot be random as other customers also affected at the exact same times.
