Title: BT Outages on 20cn
Post by: waltergmw on August 27, 2010, 01:30:04 PM
Gentlefolk,

This has been broadcast by PlusNet but it will probably affect many ISPs.

Kind regards,
Walter
_______________________________________

This is an update to this morning's announcement about widespread disconnections and authentication problems affecting customers provisioned on our 20CN 'up to 8Mbps' broadband network.

Our suppliers have confirmed that a problem this morning caused a loss of routing across their core network. Whilst the underlying cause is unknown at present, it seems that the majority of our customers have been able to reconnect successfully.

Due to the number of sessions that were dropped, our network is now out of balance. This may cause peak time performance/speed problems for some customers later this afternoon/evening when the network starts getting busier.

We are in the process of rebalancing the network and will post another update later this afternoon.

If you're still experiencing problems connecting then please try powering down your modem/router for 20 minutes or so before switching it back on and attempting to reconnect.

Thanks for that information Walter. I don't know if it's related to this, but I did have a few PPP authentication dropouts this morning.

I am not on 21CN but I did notice my router was trying to get a connection for an hour this morning.

I wonder if this is related, I am on Plusnet well for a few more days before I go back to Zen.

I thought it may be something to do with my migration.

Hi  :)


I'm On AOL LLU ( Upto 24mbps )

But I'm starting to wonder if there's something major going on somewhere  :-\

Tuesday 17th Aug... LCP Down | LCP Up .. Approx 11:00am

Thursday 19th August... Speeds Start To Go Bonkers!
Nothing wrong with my Sync  :no:
But my... Down Speed ( Throughput ) all over the place.

Friday 20th August... Up Speed ( Throughput ) .. Permanently Low  :'(

Wednesday 25th August... LCP Down | LCP Up .. Approx 11:30pm

Today | Friday 27th August... Terrible ( Down - & - Up )  Throughput ... All Day!

Oh well that is BT Openreach engineers bank holiday canceled :)

Could be government introducing censorship on the net like the USA and China are doing.
