Right, we have just worked with our hosts and confirm that there is a problem with TM at night.
The main problem seems to be in one of the routers at 18.104.22.168 which happens to be maintained by TM. This problem is not just isolated to our host but to many international sites.
TM replies to our host:
“Our link to LINX is experiencing heavy congestion especially during peak hour. This might contribute to the packet loss issue.
Our host is seeing if they can negotiate something to fix the issue but this is also highly dependent on TM working with them. We will keep you posted on further developments and we have our fingers crossed.
17 September 4.47 PM: Massive loss on the route…at about 50% loss. We are aware of the situation and exploring our options despite it being TM’s incompetence. Will keep everyone posted. I will be temporarily turning off my MSN/Googletalk to concentrate on the situation and save my sanity 😛
