BT Routing issues at the moment?

Anyone else on BT got any routing issues?

I was all working fine until about 20 mins ago.
Some sites are working like TBB, BQM is getting RED Bars, Twitter and loads of other sites partially load.

*** update ***
Never mind, it came back up and you can see how long it was down viewing my BQM.
Strange I could access these forums fine yet the BQM couldn't connect to my router, maybe the BQM Servers are located else where.

Looks like there was something going on from downdetector.co.uk

Not seen anything unusual on my BT Biz FTTP line, though i don't have a BQM setup.

There was a BT issue we saw and noticed

It wasn't just BT that had problems, on down detector there was a load of issues reported across the board

It lasted about 20 to 30 mins, but wasn't just linked to BT, VM was also affected and a few others too.

The funny thing was when I spoke to BT they was unaware of this and was instructed to go to their site to report it, sadly BT's site was also down LOL

I was also unable to connect to our server located in a data centre in France.

I did at one point think it was a DNS issue, but even using the IP directly was failing and tracerouting was failing as it was leaving the BT's network, hence me thinking it was a routing issue.

Now Netflix was working without any issues at all same with these forums, which lead me to it being a routing issue.

About 10 mins after talking to BT it slowly started to come back online, Twitch was partially down for about 40 mins for me, so I got to relax watching Netflix LOL.

Agreed, also VM was affected too.

BT, VM, PlusNet, Gamma, Zen to name a few. It was like Linx went down or stopped routing or some where like Telehouse went of line but they didn't it was very strange.

Like a major infrastructure provider (Linx Telehouse etc) had issues but there was no problem which I could find on any of them.

It does sound like a short term screw up in the routing tables that either fixed itself or was fixed by someone.

Some one put 0.0.0.0/0 and advertised it in to BGP mistaking a subnet for a wildcard or the likes

That sounds about right, when I did a traceroute all I could get to (well was displayed) was the #telehouse.ukcore.bt.net and then all after timed out.

Maybe its just me, but I have just noticed is that the hops are less than what it was before the outage, so maybe BT has routed round the issue ?

I am now getting 8 hops to the BBC Site where I think it use to be a few more like 12.

Paul

Without a before and after it would be hard to even theorise where the problem was, its fix now which is what matters

It was only BT IPv4 that I can see. My v6 continued without a problem.

v4

v6

That is interesting, I only do a BQM on the IPv4 address due to its easier to do.

That could also be why some stuff was still working.

Paul

Thanks. Interesting and explains why I didn't notice any problem but got a message saying that one of my servers had lost its connection.

Wow, we just lost internet once again and this time we lost the phone as well.

The ONT LOS (Loss of Signal) was constant lit RED and was down for another 10 or so mins.

This is starting to become a reoccurring thing LOL

Paul

Loss of signal on a fibre ONT is very different from an IP routing issue, and much more likely to be localised.

Do remember too that the broadband politicians are saying full fibre has no outages or slow downs

Hi Paul, I wonder if you could indulge me?
I'm curious why you'd laugh out loud at your issue.
It seems so many speech affectations have become commonplace nowadays.
Another one is starting every sentence with "so".
This American silliness gets in everywhere.
Cheers, Les.

You have had a break in the FTTP signal. Sounds like someone / something disconnected a splitter or took the OLT down. Nothing to do with the general internet access.

If it was only 10min it wasn't a fibre break, but sounds like someone working on a piece of kit somewhere in the Head end exchange or in the route to you from there. Could even have been a software/firmware update to the OLT with consequent network reset.

Oh I know it wasn't a routing issue, but a lot of people in London lost their connection, my EE Mobile was down as well, well the data side was down, didn't check my mobiles phone service.

All I could do is wait for it to come back up, luckily it was only 10 or so mins, but when it came back up I did a check on downdetector and seems most of London lost it at Midnight also, so not just me.

Now maybe they all might of been on the same exchange as me and it was an exchange issue I cannot tell.

But according to downdetector it was showing it down for pepople in London, some in Manchester, Birmingham, Oxford, and a few other places.

Also downdetector showed that ISP's TT, BT, Sky, EE, Vodafone, PN, and a load of online services were also down or having issues at the same time.

So maybe BT Engineers were working on some cables in London etc hence it only being 10 or so mins.

Paul

Sorry it was just my humour, was a bit miffed at the time, 2 times in a week of no issues and all around the time I renewed my sub with BT.

That's why I did a LOL.

Well Down detector showed it mostly down for pepople in London, some in Manchester, Birmingham, Oxford, and a few other places.
It also showed that providers TT, BT, Sky, EE, Vodafone, PN, and a load of online services were also down or having issues for people at the same time.
VM had absolutely no issues at the time which points me to BT's infrastructure having the issue. Maybe engineers were working on some main fibres at the time, it was only 10 of so mins that it was down.

In reply to a post by MrSaffron:

Yeah and they are also saying free full fibre too which cracks me up there.

But sure FTTP should suffer no issues with surrounding noise etc, but a break in fibres will, the only slowdown I have had was when I first got FTTP, but a quick phone call to BT and that was rectified over the phone after my router reconnected.

Paul

While down detector can be useful, it is very open to a few people making an event look a lot bigger eg. it makes no distinction between a webpage being down and the service of that provider.

This is true, but when you see "Anyone else lost their broadband" seems to point to the connection being down, But I normally just use them to see if anyone else is also having issues at the exact same time.

Paul

LINX traffic stats are a good is everyone down or a major regional event, since while not all traffic goes via LINX major events affecting large numbers will be visible generally.

My IDNet BQM for last night/this morning shows no gap.

Ha ha. I can think of a bit more pointed comment to make! Cheers, Les.

Hi Pau lelboy, I wonder if you could indulge me?
I'm curious why you'd laugh out loud at your issue say "Cheers" after "I can think of a bit more pointed comment to make!", which reads very much as if the more pointed comment would be an insult or rudeness.
It seems so many speech affectations have become commonplace nowadays.
Another one is starting every sentence with "so" "Ha ha".

Just poking fun. No offence intended. I hope both you and Paul enjoy it.

Heh. You'd hope that that wouldn't be a problem for anyone the size of BT, Virgin Media, etc. They should have full routing tables arriving at their kit.
