TTLatency

For a while now we've been seeing latency jumps on TalkTalk connected lines.

Examples:

Here are some examples:

• 
  Jump down at 9am
• 
  Jump down at 8pm
• 
  Jump up at 10am
• 
  Jump down at noon
• 
  Jump down at 1am
• 
  Jump down at 1am
• 
  Jump up at 9pm
• 
  Jump up at 3pm
• 
  Jump down at 10:30am
• 
  Jump up at 1am
• 
  Jump down at 6pm

When does this happen?

This typically happens when a lines is moved between LNSs at our side.

Why does this happen?

In simple terms, TalkTalk run a ring network, and traffic and go around it one of two ways. One direction is shorter and the other longer - hence if your circuit is being routed on the longer path, then the latency will be higher.
