That is a bugger, I hope they sort it out!
@Afriman, if the correct redundancies were in place in London there should not be repeated issues which have been noted by some around the MTN service (to be fair not validated). It seems a lot of your loyal customers are worried you have been sold down the river by MTN. Jumping back to the London issue, you say it was upstream from MTN, so was it a direct service provider to Afrihost or one of MTN's suppliers?
Just to add a note, I have personally seen some issues on Afrihost in the last while performance wise. Maybe something you could answer is why ondemand.dstv.com content is mostly not able to stream properly using Afrihost? What is your local peering situation now that you have moved to MTN?
