Hi.

Tower 110 Linksfield was down today for most of this afternoon.

I have lost all my emails.I know for a fact coz many people tried to send me emails today and they got some undeliverable message.

Now I am worried if that I have lost a bunch of emails that were unchecked in my mailbox before tower went down.As when I checked I had NO emails.Which was impossible

Anyone have any idea where emails would go to if they were in inbox before tower went down?

Maybe its late, and I'm not understanding you, but if E-mails are in your INBOX already, its a local problem, and has nothing to do with tower!

And on the other side of things, a tower failure could have nothing to do with mail getting lost, it is only a connection medium, a hub of sorts, I don't even think it has an IP, to put it in english, TOWERS HAVE NO INTELLIGENCE - as I'm sure some people think about me[:0]

mail sits in a pop server at comfy sentech offices, generally, the options for removing a mail from said server, involve client downloading the mail, then deleting it from server.
my guess is that sentechs mail server was down for a brief (maybe extended) period today, maybe a DNS failure (there seem to be a lot of those lately).
Emails that came back undeliverable, will have to be resent!
A tower being down, and mail undeliverable are 2 independent events, one cannot have anything to do with the other.

OK, I just had a thought, are you referring to your sentech mail, or are you running a mail server off mywireless, if its the latter, the 2 are directly related.
 
sort of correct dorris ;-) ... Sentech's towers (IPWireless) are actually quite capable of doing some pretty "intelligent" and fancy things ... it would however seem that Sentech are not making use of this (or haven't figured out how)...

As to the rest = pretty good ;-)

Doing intelligent things such as?
 
Well, for one, there was talk a while back about towers keeping some sort of routing table, and if the target is on the same tower as source, not sending signal all over network, on a crazy loop, but just linking the users from the tower, the best part about something like that would be full speed (3Mb), I can't remember if the reason its not happening is because the towers don't have <i>the intelligence</i> or if it was simply the administration nightmare from Sentech side.
and that is an example of some intelligence at the tower, obviously, we would never see something like that implemented here.
It really doesn't sound like anything too dificult, assign IP's according to tower the request came from, To the best of my knowledge, thats how Telkom organises ADSL, users on the same DSLAMS get the same IP ranges, come to think of it, Telkom could also organise something similiar on ADSL, but not in this country, those b@st@rds can't even allow phone calls on the same exchange for a penny less than a call routed through 20 different exchanges.
 
The NodeB's on the Towers have a fair amount of intelligence if used.
Mainly the switching and recognising of short and long range connections.
The main and nice feature is the capping.
Basically as standard, everyone is given a 3 mbit pipe from their modem all the way to the server where the 128, 256, and 512 capping is implemented.
Should these packages however be split into different IP ranges then the capping can take place at the Tower thus allowing many more users onto the system - nuff said [:)]

Guess that answers the change in IP ranges issue

ProAsm, you say capping is in effect at the tower level now, does that mean that a 128K user is given 128K total between himself and head office, or 128 up/ 128 down.
I'm asking because I noticed a few days ago that my uploads wreak havoc on my download speeds.
 
Dorris,

I mentioned similar constraints on total open TCP sessions... When the capping was only occuring at the server we (as customers) had a somewhat better capactiy to handle multiple threads.

Oh well, at this moment I'd just hope for stability in performance .....

PROAsm - this may be worth mentioning to you... since the helpdesk didn't begin to understand my comments....

Since the implementation of the ip range changes (and therefore the tower based capping) my latency has gone for a ball of wax.

Pre-changes latency (ping response) to ITWeb/Sentech/IS web servers were averaging between 180ms and 220ms (excluding spikes)... Since the move my latency seems to be sitting in the 380-420ms range...

Could you have a look yourself and if valid possibly raise at the appropriate forum ?

I did not say the capping is being done at the Towers, I said it does have the capability.
