High ping times in evening to specific server.

Hi.
In the evenings since some time last week ping times to a host in france which i connect to for things that require low ping (ok...it's gaming Smiley) have been very high, 150-200ms. Usually it's around 16-22ms and I have no problems on the old network.
The new network however seems to use different routing into the hosts network and from around 7-8pm till 10-11pm the ping times go quite high.
  7    12 ms    12 ms    12 ms  core1-BE1.southbank.ukcore.bt.net [195.99.125.130]
  8    13 ms    14 ms    13 ms  peer1-et-10-1-0.telehouse.ukcore.bt.net [195.99.127.3]
  9  139 ms  138 ms  135 ms  be100-104.ldn-1-a9.uk.eu [178.33.103.232]
10    19 ms    18 ms    17 ms  be11-1187.rbx-g1-a9.fr.eu [91.121.128.86]
So yes it's just between hops 8 and 9 where the issue lies...is that a problem with BT's network or the hosts network or both and is there anything plus can do about it? Smiley
New network woes...different routing...sigh Smiley

Errrm, NOPE !
The ONLY hop which matters is the final one,  i.e. the host which you are trying to communicate with.
Each line of the traceroute just shows the individual reply time (to PING requests) from each router along the path, back to your PC.
The PING latency along the route is not cumulative, so it doesn't matter that on your hop#9 takes a little longer - it just means that particular device is a bit slow to respond to PING requests and doesn't necessarily mean that that device will also be slow at processing your traffic.
If all following hops (after #9) were also similarly slow, then that would provide an indication that the connection to hop#9 is either slow, or perhaps is a long distance away, but they aren't - so don't worry about it !.

What is the domain name (or IP address) of the the host you are trying to reach ? - so others here can also try tracerouting to it.

Re: High ping times in evening to specific server.

except that the high ping times on that hop coincide with high ping times to the game server
outside of the specified times both pings to that hop and the game server are fine
also the server has disabled ICMP so any hops after what I've pasted will time out but if you want a go it's

*edit*
and it's back to normal

Yeah Nibiru you're on the old network so taking a different route

Re: High ping times in evening to specific server.

But presumably that just means that all my traceroutes will be slower than yours, but I should still see the large variations in latency you are describing beyond the Plusnet/BT routers ?.

Re: High ping times in evening to specific server.

Niburu is correct in that it's only the last hop that shows you the latency to that server. It's likely that the devices along the way aren't set up to prioritise replies to ping traffic, so the response times on those are higher.

Re: High ping times in evening to specific server.

It's still more than coincidental that high pings to the destination server coincide exactly with high pings on that hop though...ho hum Smiley

Ah well, pings been on the rise again since ~7.30pm...it's very odd Smiley

The rising pings to the server do coincide with that 9th hop rising too so i dont know

Re: High ping times in evening to specific server.

It is very odd that we both go via  "vac1-0-a9.fr.eu"  but your pings are massively different from mine on that hop !  Crazy

Re: High ping times in evening to specific server.

interestingly before you hit VAC (which is OVH's DDoS protection) you're routing through
7. be11-1188.rbx-g2-a9.fr.eu
whereas i'm hitting
10  be11-1187.rbx-g1-a9.fr.eu
Looks like it's really in OVH's network then, ho hum Smiley

Re: High ping times in evening to specific server.

Also, this is an annoyance with the new network...
Seemingly permanently connected to the same gateway on the same IP subnet so you can't gateway hop to see if you can get a better connection...
The old network was seemingly better for my needs :p
