James.
Can I perhaps ask you a Q which you may (or may not) be able to answer, because its not really specific to PN/RIN
Since I moved web hosts, over the past couple of weeks theres been several times when the forum "white pages". Ive contacted Vidahost about this and they say all is well and whilst I was on the phone to them one time and the site whitepaged they asked me to perform a tracert.
... which showed that a particular hop was experiencing high latency.
If I'm quick enough each time the site white pages, and I perform a trace then the same hop would also appear to show high latency. Its repeatedly the same hop.
Vidahost have been pretty good - I cant really fault them, and theyve rung me back a couple of times but since its not their network then I pressume its out of their control.
The site has just this min white paged again for me.. and sure enough once again the same hop breifly showed high latency. This is what I got immediately after the white page ...

Just whose responsibility is routing and peering and who gets to kick whose buts on this?
(bleedin yanks - cant even spell london? - peer point is NTT America)
-
Hmm. Does your host not use the peering supplied? Or is it completely unrelated to them?
I suppose it depends on whether or not they pay that peering supplier for their services. If they do, then it's Vidahosts responsibility, if not, then it's probably a best bet for you to contact them directly.
Or just come back home once the CCGI upgrade occurs. The white paging is a bit annoying :(

>> Hmm. Does your host not use the peering supplied? Or is it completely unrelated to them?
They say unrelated- this seems to be smack bang in the middle of me leaving BT and going over to the hosts. Its not their network (thermalthree), nor their routing via misp.co.uk
Problem seems to lie after we come off colossus > linx... and in between verio.net and nnt.net.
Problem router is here:- xe-3-1.r01.londen03.uk.bb.gin.ntt.net [129.250.2.46]
I'll contact them again tonight as I need to go out again soon.
>> Or just come back home once the CCGI upgrade occurs.
Got used to the nice XPanel and own subdomain designation so I can now have http://forum.kitz.co.uk
and also can you cope with my bandwith/hits usage ;)
>> The white paging is a bit annoying
I know :/

Where's the trace from and to? I'm guessing your tracing to kitz.co.uk?

Yep. Tracing from here to the domain.

As discussed, I don't even touch your dodgy hop.

NTL/Virgin also gets this problem. It looks like the problem is with the step-off at the other side of the t'atlantic ocean.
I also get the whitepages occasionally. Smokeping shows that the problem is likely going to be worse 12-6 US time (1700-2300hrs) as below (if hotlinking image works):
(https://forum.kitz.co.uk/proxy.php?request=http%3A%2F%2Fwww.dslreports.com%2Fsmokeping%2F.simg%2F__navcache%2F117507879831410_now_1174970760.png&hash=0198b3a13f69e9b5bd733d1048b97d619274ac6b)
I strongly suspect there is little your ISP or hosting provider will be able to do about this unless they have another data centre elsewhere.

I get whitepages at any times of the day, including when all Maericans should be asleep.
-
Thanks for the feedback guys. - appreciated.
Ive just removed a mod script from the forums that runs - just to make sure that it isnt the mod thats causing the errors.
Vidahost has been back in touch with me and they cant find anything at their end but have offered to move me to another data centre if the problem continues.
Continuing to monitor today.
-
Just whitepaged again, sorry. >:D
-
damn :/
Been ok here so far.
Oh well at least it wasnt my script lol
-
Has anyone had any probs since.
All evening things have been really snappy and despite me deliberately trying to get a white page and hammering the forum, I havent been able to.
-
Been okay here since too.
/me casts suspicous glance at Vidahost

mumble mumble under breath - also been ok for me since I removed some code from the forum template which ran fine with my last hosts.
$cgiserverip = $_SERVER['SERVER_ADDR'];
$cgiserverhostname = gethostbyaddr($cgiserverip);
$server_details = 'Server IP: ' . $cgiserverip .
' Hostname: ' . $cgiserverhostname;
echo '<span class="smalltext">' . $server_details . '</span>';
echo '<span class="smalltext">';
passthru ('uptime');
echo '</span>';
... which is basically a script which tells server info and load times.
It ran perfectly on the old ccgi server, but when I moved over to vidahost - they dont support the pasthru command for security reasons, so I was getting a lot of errors in the admin logs, so I simply commented out the line
//passthru ('uptime');
This morning I deleted the whole script so it doesnt give any server info at all... and since then things for me at least seem a lot better, although I dont see anything in the script which would cause such problems.
James has said its whitepaged for him once, and Im now hoping this was a one off.
About an hour ago I was hammering the forums, and chris had a small script running several thousand lookups to try and see if we could stress out the site/server... but it coped fine.

I haven't had a white page since I changed browsers about 10 days ago, but I did sometimes get a longish delay on clicking a link. Now the site seems much more responsive, and I haven't had any delays this morning.

Just whitepaged again when clicking on "show unread posts"
-
Just got one now attempting to see the thread on this group (ISP's)
Havelock
-
thanks for the feedback guys - keep it coming.
If it continues I'll ask vidahost to try transferring me to one of their other data centers... although I need to double check locations first since I want to ensure hosting remains in the UK.
-
Since I posted my earlier message, I'm now finding that things haven't visibly changed, and there's sometimes a very slow response to clicking a link.

I got a white page a few minutes ago on entering the site. A traceroute included this:

okay thanks eric.
I didnt ask vidahost to move servers, since I was away for a couple of days and didnt want them to do that when I wasnt around.
However, can I ask - are things much better for everyone else? Reason I ask is that I honestly havent had a single white page since Wed morning (although I appreciate I wasnt here Fri and sat).

I've been seeing quite a bit of whitepaging this morning, whilst trying to make a post in the introductions thread and whilst trying to read page 2 of this thread.
Here's a traceroute from me:

okies ty..
I'll get back on to vidahost and see about moving to one of the other datacenters to see if it can bypass that particular hop.
I want to know where its going to be hosted though first tbh. :/
[edit]
Contacted them to ask where.. and got a reply back in under 6 mins. 8)
In view of the fact there may be some inevitable downtime whilst the move is performed, trying to negotiate the best time to do this.
-
Not had time to do anything about this yet as Ive been so busy over the past few days....
But Ive just been informed that my site has been linked to on slashdot - so guess we will see how Vidahost (and my bandwidth) performs.
Just had a look at my stats and beginning to see a few hundred visits coming in from the US. Im not sure what the time difference on slashdot to my stats are though.
Cause I try and keep file sizes relatively small it doesnt seem to have had a major impact on bandwidth (I get circa a 100k hits per day as it is).
-
Is anyone still having probs with this?
I havent seen anything for several weeks now and its all been ok here.
-
Sorry Kitz, but I had a white page yesterday. There was nothing odd in the traceroute.
Eric
-
damn :/
Thought it was sorted.... can everyone do me a favour and report in this thread anytime they see this please.
-
It was really slow at about 8am today ... I got one "page cannot be displayed" but other than that, it seemed fine.
I wish I'd checked the other website hosted here at the time to see if it was slow too. Might just have been a general server issue.
It speeded up shortly afterwards and it's flying now.
