I'm sorry to hear your connection speed and ping have been out the past few days. It's not good when the connection is that badly impacted, I feel your pain.
I've checked the network for you, it does appear there were some issues on the cable that would explain the problems you were seeing. I've had a look at the cable in the past 24 hours and things look to have improved. Are you still suffering the same problems? Let us know and we'll investigate further if there's still a problem.
