ppp outages

anyone else on the trial getting outages during the night on their ppp sessions?
I assumed was the trial but I checked another plusnet trialist tbb graph and they dont have the same outage. mine here.

note this outage is on ipv4 as well the entire ppp session was down.
I had a similiar outage on the 1 feb as well.
If you can see 2pm outage from yesterday ignore that (engineer visit).  I am reffering to the one at dusk.

Re: ppp outages

Probably just maintenance work at you exchange?

Re: ppp outages

Connection drops during the early hours are "normal".
It seems BT see no problem doing lots of network maintenance and cutting large numbers of users off for a short while - and most days as well. At work I monitor a proportion of our customer's connections (mostly the ones important enough that we'd like to know there's a problem before the phone rings), and I quite regularly see a cluster of them go offline early morning - sometimes for a few minutes, sometimes for an hour or more (but that's not too common). I did query it with the wholesaler once, I got a reply back (around mid morning) to the effect that "so far today I've got 20 notices of work for tonight".
There doesn't seem to be much of a pattern about it. Sometimes it's just "random" customers, other times it's "most of them" - I guess it depends which bit of the network BT are working on.
The message to take away from this ? If you rely on your connection (as in it's business or safety critical) then don't rely on ADSL ! One of the things you get when you pay many times more for a "business grade" connection (apart from the several hundred quid a month bill) is an SLA that means they'll fix it it if breaks. With ADSL, apart from these routine drops, if it breaks then they can take a week to fix it and there's nothing you can do but sit and fume. Explaining that to customers can be "challenging" - especially the ones that refused to pay for a business grade connection to their business centre and now expect you to wave a magic wand and get all their tenants back online "yesterday" Roll_eyes

PS - having read the additional posts while I was writing this, your sync with the exchange will be fine, the work is "somewhere" in the network between you and your ISP.

Re: ppp outages

to me isnt normal, I am used to uptimes lasting several weeks.
and an outage lasting 40 mins or so isnt normal.
I attached log to above post now.
basically if noone else on the trial had this I will make a support ticket with plusnet to get an answer on the cause.

Re: ppp outages

Most customers will have uptimes of several weeks - BT do a lot of work overnight around the country but that doesn't mean the same customers are cut off night after night! Smiley
You'll still have DSL sync as that comes from the cabinet but there's a lot of BT Wholesale systems between there and PN that may need work.

Really?  Aren't PN support overloaded enough without answering why a connection went down during a maintenance window, came back up and is working perfectly...

3 times in space of 4 weeks is excessive.
if its due to trial and something plusnet did no problem, as I accept it been a trialist, if its due to BT on normal paid for service, its excessive.
telling me it 'may' be this or that isnt too helpful.
Its pretty obvious its either maintenance or a unplanned outage, thats easy to guess.  The question is what it is exactly.

Re: ppp outages

I can't see anything for that area code.
I don't think it was PlusNet's end because no one else seemed to have those brief outages on their graphs.
There could have been some unplanned maintenance work at your exchange, or further upstream. The 13:30 one seemed to benefit you as it lowered your ping according to the graph.

ok thanks for checking andy, out of interest is it easy for me to check somewhere on a site?
I will ask plusnet if they can find a reason for it.
I am assuming the latency change was due to changing plusnet gateways as each gateway has different base latency.
As a reminder the afternoon outage was an engineer visit, my modem was unplugged.  I am talking about the 1.20am to 2am outage.

Re: ppp outages

If there is an outage between 00:00 and 06:00, then it is normally always some kind of BT maintenance. It's not too uncommon to have multiple outages in a month, particularly if BT are doing some major work at your exchange or nearest node. It is normally fairly minimal though (5 min outages etc.)

While it's unusual, it's not anything you'll get anywhere with. Like I said, it's one of the things that comes with the low price tag of ADSL.
If you want a service with guaranteed uptimes and advance notification of any maintenance then you can have it - but you'll add at least one zero onto the monthly price.
