PPP Weren’t Down!

Category: PersonalChrisM @ 2:33 am

I meant to update the situation since my PayPerPost And SocialSpark Down Again? post. It turns out the problem was at my end, as many other sites were also not available. The sites resolved OK, but they just hung with the connection established, not even timing out. After running through the obvious preliminary checks, I asked Ira to contact our pseduo-ISP, and check what the problem was. Nothing at all apparently, the fault must lie with our setup.

I sent this letter, and was happy to receive a reply, quite quickly, on a Saturday afternoon!

(his name removed),

I believe you spoke to my wife, Irina, earlier today. These are the details of the problems we have, I look forward to hearing the solution.

Are our current internet problems because we are on the restricted speed connection right now, as we’ve gone over 10Gb?

This has been happening since Wednesday, possibly one or two days before that.

Problems include…

1) The following sites not working –

http://support.microsoft.com/
http://bitcast-b.bitgravity.com/websitedown/index.html
http://payperpost.com/
http://socialspark.com/opportunities

None of those sites will load, it just states ‘waiting for (name of site)’ constantly. All sites load if I use a web proxy service to test them.
Other sites load ok, the ones given are just examples I’ve noticed so far.

2) MSN Messenger can not connect, but Skype is OK.

3) BitTorrents cause complete failure with the internet connection – ALL downloads/uploads, not just torrents will stop for 10-20 seconds, start again for 10 seconds, then fail again in a loop. This has always been the case, not just since Wednesday.

Attempts to repair or specifically identify the problem…

Confirmed that no proxy server is set, Automatically Detect Settings unchecked, used both FireFox, Internet Explorer 7, Pocket Internet Explorer and NetFront.
I tried the same things on my wife’s laptop, with both a wired LAN connection and WiFi. Exact same problems occur.
I tried the same things on my PDA, using WiFi. Exact same problems occur.
I obviously tried restarting the PCs & the router (a Netgear DG834PN).
I checked the MTU is not set too high (currently 1492) and therefore causing strange fragmentation problems.
I removed the DNS servers I had assigned (OpenDNS, as the ones in this country are quite bad), and used the default ones supplied by Bazis, as well as defining the router itself as the DNS server (which would only cause the PC to use the default Bazis ones anyway). This was done both on the PC and the router itself.

The problems remain.

These issues occur on three different devices, with different DNS servers set, I believe the fault lies with either your or Kazakh Telecoms network hardware.
I did not think that resetting the TCP/IP protocol stack would be worth doing, as all three devices would be very unlikely to suffer from the same problem at the same time.

I used to work for an ISP in Britain, as a Senior Technical Support Agent, so I hope I have told you all the information you need to fix this problem. If there are other tests you want me to carry out, please tell me.

If you have a modem that you want to test in this flat to confirm the fault is not here, I would be happy to help.

Once I actually read their reply, I wasn’t exactly over the moon…

Chris,

Reinstall operating system Windows
or restore her(it) with help of the load disk. Probably after attacks virus she conked…
Earlier beside me was such problem, was not opened mail on www.yahoo.com
If you want that I came to you home and has tested on my notebook, I with joy to you will come…

About 10 GB… There is quota In Kazakhtelekom to speed on loading more 10Gb.
You it is necessary to call me 688-907

Krasnikov (name removed)!

I should point out straight away that they said they didn’t speak English (not a problem, it is to be assumed in this country), but I really hoped the letter I’d sent would give them enough information to not get a ‘reinstall Windows’ reply. Anyway, at some point last Saturday something happened that caused the sites to work again. Whether it was something corrected at Bazis, or further on up the line with Megaline (the real ISP) noticing that some of their hardware wasn’t working, I’m not sure. Anyway, sent this reply…

Thanks for your advice.

Reinstalling Windows really is a last ditch ‘fix’ for any computer problem. The fact that these sites did not work on THREE different devices (XP desktop, Vista laptop, Windows Mobile 6 PDA) indicates this would not have done anything to remedy situation. All three devices are confirmed as virus, trojan, spyware, adware and, in general, malware free. I’ve not encountered any viruses in the last 15 years that prevented that sort of range of sites from loading.

Luckily, at some point during Saturday afternoon, something was fixed somewhere, and the sites worked again. Perhaps Megaline had a routing problem or flakey hardware that is now fixed?
Anyway, I’ll wait until the end of the month, when I get my ‘normal’ speeds again (I understand the 10Gb limit, it is laughably small, but I understand it), before retesting to see if BitTorrents still cause catastrophic failures for all internet based traffic.

Thank you for replying,

Chris Merriman
