It just happened there again, on off for a few minutes? My router was reporting all fine until final 'stage'
(ie. couldn't see DNS servers) and when I did a tracert to plusnet DNS server was getting:
1 95 ms 199 ms 198 ms [my router]
2 63 ms 41 ms 42 ms lo0.plusnet.thn-ag1.plus.net [195.166.128.101]
3 * * * Request timed out.
etc
When it works it's 6 hops.
- strange high result to router but ping is < 10, I'm not toooo worried about that.
Surely I'm not only persons who just seen this? Bit worrying twice in a week and nothing
on service status. Nobody else seen this? Anything to worry about?

Forced a resync at my end a few times. As wasn't sure if problem was local or remote.

My girlfriends PN connection went intermittent starting about 17:30 and seems to have stabilised after about 45 mins. Oddly when it worked, downloading pages from the web were ok, but the minute we tried an upload e.g. broadband speedtester it lost sync. Also could get as far as the PN portal login screen entered username/password hit submit and crashed for a few minutes.
Mine seems to be fine and were both off the same exchange but haven't delved any further.
Cheers,
Pete

Unfortunately, we saw 6 segments (a total of 930Mbps) drop last night. Whilst those affected would have been able to reconnect pretty much straight away, the load on the rest of our platform would have been considerable and will have added to speed issues that were seen last night.

like PPP refused (or was it dropped) by peer.
And now about 25 minutes ago it has just dropped on me AGAIN, this time the symptom was the connection to the gateway went
down for 10-15 minutes, though it is now back up again. This is more like the intermittent error I reported in this post,
that others also apparently have been getting. Yet strangely service status never mentions any problems?
Complete loss of Broadband for 10-15 minutes every few days or so is going to get pretty irritating pretty quickly!

They have been 'load balancing' (see service status).
I would check your speed though - mine has gone through the floor since the reconnection.

Quote from: martin2006 wish i knew what all these letters and numbers mean
I will try ...
The wikipedia entry for DNS ( Domain Name System) is very comprehensive, but is quite deep
A feeble attempt at a simple explaination follows ...
Take the BBC webserver as an example (its IP address on the internet is 212.58.224.138 )
Now, if you want to access the BBC website, it would be a complete pain to have to type "212.58.224.138" into your web browser.
What you want to do of course is type "www.bbc.co.uk" !
So, the concept of Domain Names comes in to play.
It allows the association of well known names (i.e. bbc.co.uk) to IP addresses ( i.e. 212.58.224.138)
So, when you type www.bbc.co.uk in your web browser, the first thing that your PC has to do is lookup the IP address of www.bbc.co.uk so that it knows
where to send its data to ....
This is the DNS Lookup phase, and for most people on plusnet, their pc will ask the plusnet DNS servers for the IP address.
Normally, they respond and all is well.
However, if they don't respond in a timely manner (or respond at all), your web browser doesnt know where to send its data, and hence will pop up the "server not found" or similar error pages ...
nslookup, the output of which I posted above, is a tool to ask the pc to lookup a web address ( using DNS) and show the results.
It can be a usefull tool to see whats afoot ....
Hope that helps .

You were disconnected because of this (notice the 'Administrative reset' entry in the RADIUS logs below for your account):
unknown (Administrative reset) 212.159.XXX.XXX Not set 07:30 31/Oct/2009 21:05 02/Nov/2009 2 Days, 13:34:47
Quote from: martin2006 hi, can i jump in on the end of this although i am not following most of your technical stuff, i keep getting intermittent connection problems, ie i access a web page and it comes up with the page saying i dont have a connection, then try again and its fine. also when i do a send and receive on my emails, sometimes it shows that nothing can be downloaded as if there is no connection, then click send/receive again and its all fine. is this a similar fault as i have also been having speed and ping problems.
i have attached a file of the diagnose connection problems which i got this morning but would appreciate any help or advice
Try a reboot if you haven't done so already Andy - you've been online for a few days now and we've had a few problems during that time.

I did some gateway hopping last night when you said you thought it was routing issues, and it didn't seem to make any difference.
I'm fairly certain I tried Plusnet 6, Plusnet 10, Plusnet 11 and Plusnet 12, though I may not have remembered correctly. I know I connected to all 3 data suits at one point or the other (ie Telehouse East, Telehouse North and City Life).
Not at home at the moment.
