Latency/ping times query.


[link to this post]
 
For my connection would it be too much to assume that an increase in latency/ping times is due to Plusnet putting Madasafish users (my exchange is 20CN) onto IPStream Connect (IPSC) to link to the rest of their WBC setup?

This was done a few minutes ago:-

Ping statistics for 212.58.241.131:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 61ms, Maximum = 63ms, Average = 61ms

Previously the average would be around 46ms.

An earlier 2Meg connection from madasafish had an average of around 23ms, but it was fast path.

Your numbers look similar to my BT Business Broadband lines on 20CN only exchanges in Scotland.

It's on and the downstream and upstream depths are the same as they were eleven months ago according to data from the DMT tool.

Have they increased at all if the connection has changed to IPSC WBC?

Update


[re: Apprentice] [link to this post]
 
Following the loss of my internet connection (no issue with exchange sync) from around 10.45pm last night and into this morning, all was back to normal when I checked at 11.55am, even the ping times/latency had gone back to around what it used to be:-

Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 48ms, Maximum = 50ms, Average = 49ms

Wonder what happened?
