Something somewhere fishy going on

[Frankc]

I am already on ADSL for more than 2 years and work almost permanently online. Purchased a new Telkom modem few months ago and with 1024 ADSL line everything works fine.

Couple of weeks ago (shortly after Telkom "upgrades" their 1g lines to 4g) I however started to get a hell lot of dropped lines and also noticed that a lot of other mybroadband users complain about the same thing.

Something interesting that I noticed is that the line drop when just Outlook Express are running to download my 32 emails. The line drop over and over again even if I restarted the computer but, if I also open internet explorer while downloading email the line don't drop.

Right at this very moment the connection to my UK servers are SO slow that it took me easily 20 minutes to perform a Cpanel action. It's definitively not the server because the server load is at 0.15 (4 cpus)

Due to above I started to think that something fishy is going on and that Telkom installed some software during the upgrade to 4g lines that caused these problems.

Why the hell would so many people, that don't have such problems in the past, now all experience all this crab? With typical Telkom logic it seems that they "give" you increased ADSL speed to local, or perhaps just internal Telkom network and at the same time reduce, limit the speed or access to international networks. (Local broadband cost them nothing while they pay for international broadband so it would be a clever move to improve the one and degrade the other)

By the way. It's only certain connection types to Uk server that's as slow as hell.

Website loads fast. Access to Cpanel services almost dead and so are FTP access too while email connection is just a little bit faster than dead.

No way guys.

Telkom MUST have software or filters that limit the connection speed etc of certain services.

There is no way that http access to a server can be fast enough while FTP and Email access to the same server is beyond dead. (Dual Xeon 3.0Ghz with 2GB memory running at only 0.15 server load)

Can you say "shaped line"? Looks like Telkom is shaping the traffic to favour http traffic. Why do you use Outlook Express? Try Mozilla Thunderbird, much better, and have a lot of extensions to enhance it.

Also seeing this - massive shaping.

I basically can't get more than 1mb/s out of my line for anything except http. http's the only thing that *sometimes* burst to more than 2mb/s

They also seem to be limiting the amount of established connections you can have... Download a couple of torrents at the same time (high amount of established connections), try and open, even a local web site... Dead slow

The fact also that they upped the downlink but no the uplink speed... If your uplink speed is saturated, your downlink speed will be *much* slower.

In essence, don't do anything on your 4mb line, and you'll get 4mb Typical telkom

Does cpanel by any chance run on anything other than ports 80 or 443? Then it's probably shaped to hell. I noticed that Telkom has increased the shaping lately (I thought they were supposed to remove it). I have the same problem getting into ISPconfig on our UK server. But hey, we have it easy - try those non standard ports on iBurst. You'll cry.

Another which might impact on this, is the international packet loss. I've seen this at a number of our ADSL-using clients. Local pings are fine, but if I traceroute, say www.google.com, roundabout hop 6 or 7 latency increases by about 250ms and packet loss start.
