The official:

We've been investigating the ping spikes. It's been a curious one and what hasn't helped is that the issue has lacked consistency in that most customers seem to be unaffected. Mostly gamers (and not all of them for sure) seem to be affected for obvious reasons.
Though not yet confirmed, we suspect the route of the cause could be a faulty interface card. We're just waiting now for more data from some intensive debugging reports we've been running and then we should be in a better position to decide on the best solution. The ping spikes are almost certainly caused by the BGP scanner, though this in itself is not unusual and has proven to be a red herring, only the spikes are higher than would be expected which suggests they're the symptom of another issue. All configuration modifications to date have yielded little improvement which is leading us to the conclusion that we have a faulty interface card which may simply require replacing.

We're almost there but we want to be certain before we take the necessary steps to fix.


Any affected, sit tight for a couple of days. If no joy, post here or PM me and I will press for more info ;)

Hi, my pings are back down to 27ms which i am happy with buy any less and i would be in amazement

Jeff thanks for the info.

My problem is not the spikes its the fact i can no longer get a low ping under 50 that i always got until a couple of weeks ago.

Is this caused by the problem mentioned in your post and when the spikes issue is fixed  the pings will drop?

Bill

Yeah, that's what I got from Tim on Friday, I posted the gist of it on the AG board.

I have also seen a massive ping in the 3rd hop sometimes

mrapoc

i always get high pings in the 1st  ???

Bill

That's your own router !!! :o :o

yeah, I noticed that! His router is taking 199ms to respond to a ping on his lan. Should be virtually instantaneous. Summat wrong there.

maxping

Have just been to my brothers who recently changed to Orange BB and i did a ping -t and in 15 mins he got 23ms at the lowest and 35 highest , i wish i hadn't gone to see him now , and the phone he got free is a cracker.  :'(

Do you have a Speedtouch router?  If you do it's a route tracing anomaly and nothing to worry about.  Try ping 192.168.1.254 and that will show the true latency to your router.

This was 5:30pm on Friday night so hopefully their continued testing will have thrown up some useful info and we'll hear more as soon as...

Ill do a few traces etc in a sec...im finally at home sitting at my pc! just in time for i28 aswell!, as for how i fixed it...ill copy the post i made at my "Planetside outfit's forums"!

QuoteSorted  - kinda,

Basically, the error in the memory is on one stick of DDR400 Dual channel (1GB) - When tested alone, single channel, the error does not show, however when running them together, it does. The error shown is a 4 Bit error on the same address each time. Now, i assumed that this might not matter for the time being, although somethings may and will crash the computer...i dont think planetside and alike will! - why? Basically its down to parity bits. 1 wrong parity bit, then you get your error. But, its 4 error bits, so, the parity bits will cancel each other out - as far as the games concerned its fine, provided that segment of memory is only being read and not written (often, prone to errors) it should be ok.

The error itself is just over 1500mb, so, i dont think planetside will use that much up anyway

Hi Guys

Two weeks is a hell of a long time! It took me from 08:30 to 23:00 just to read, only reading, emails and forum posts! I was of cross-eyed and crooked-back by the end  :)

On the ping-spike thing. We can see it but we don't know what is causing it. We have had Cisco looking into it too and some outside consultants.

We are treating it as high priority even though it only affects ICMP packets. TCP packets are unaffected.

More when we know it.
Cheers
Simon
