Eircom problems again

h2s

Looks like old Eircon is having problems again. BB not working properly, some site available and others cannot be reached.

I feels like the same problem that occured a couple of weeks ago when they lost some connection to a router.

Anyone else suffering?

6th

Am suffering here but maybe because I've jjust moved from NTL to eircom and not too sure what I am doing? (setting up wireless)

cloggie

My Eircom wireless connection seems to work okay, a little slower maybe...

hamster

Yes I can confirm this. Right now as a matter of fact.

Others work such as boards and ryanair and google. Just like a month ago.

ssh

Same with me - no connection to any telia networks (hence no WoW :-p)

I know the sites are working though because I have shell accounts on servers on other networks and connectivity is fine on those.

half the internet is not connecting for me(for example bbc.co.uk).
was fine until about 30 mins ago

One piece of advice, do not use Eircom DNS servers use OPenDNS - 208.67.222.222 & 208.67.220.220

Yeah, I'm seeing it too. Different router to the last time if memory serves (83.71.112.202 this time, thought it was different last time). Can reach most Irish sites fine (I'd expect via INEX) but most international sites are unreachable. Using a proxy should be a temporary fix for web browsing, its working for me.

Also seem to be having problems connecting to international sites here. Boards seems to be the only site not giving me problems.

Changed to OpenDNS but still not 100%,must be an international link gone ?

Just spent 40 mins on a mobile call to eircom, had some guy "with a degree in network engineering" laughing at me and saying it was my firewall and claiming i was insulting his intelligence by saying it was a routing problem.

He eventually realised it wasnt my settings when i explained what a tracert was and then hung up on me when he agreed to transfer me to his manager.

I love eircom.

bbc seems to come and go for me. I can get cnn though.

Can anyone get http://home.skysports.com/
cos it wont come up for me, yet i can get skynews.

EDIT: bbc gone now.

EDIT:Google search not working now either

Ok im connected to wow now,opendns sorted it.
The funny bit is i only changed from opendns to eircoms recomended yesterday.

Scratch that,as soon as i alt tabbed back into wow i was disconnected and cant get back on.

They are some chower of sunts. There was a time many years ago when Eircom's support was indeed vey good, I used them a few time and was very happy with the response. But in recent years they are terrible, they will always do their best to blame your setup, or the classic "you may have a virus" rather than accept that there may be a problem their end.

I am glad I do not have to use them much as the BB here from Eircom is excellent, with top speeds, except when you get glitches like today.

As I said elsewhere they big prob here is communication - keeping the punters informed if or when a problem does occur. Sh*t happens from time to time, everyone accepts that, but telling lies ("we have no problem here") or just turning a deaf ear really pisses people off.

Thrill

Can anyone get Google search to work?

I've been trying for over two hours now and no luck.

Dcully

I logged into wow 40 mins ago,then got disconnected with the same problem as earlier.

Yeah Google is working for me.

netman

I tried switching to OpenDNS servers, it's even worse than eircom's own.

I'm guessing since the link went down on saturday evening we'll be stuck without it for the weekend.

I logged into wow at 7pm and now its not working. Not ringing support to go through the whole "lets reset the router and your settings"

HI people

When diagnosing this kind of issues there are several steps to take:

First ping the unaccesible web site lets say google.ie

ping google.ie

if you get a reply thats fine, not a DNS issue probably something else (i will explain later)

if you dont get a reply then ping google.ie ip address x.x.x.x, if you get a reply then its most probably a DNS issue but this is very unlikely to happen or at least if very unlikely to happen and they dont knowning it..

If thats the case then it should be enough if you enter DNS servers manually.

If you dont get a ping response then it could be firewall. Run a trace that will tell you more.

Anyway going back to the first part, if you ping the DNS name (google.ie) and you get a reply then, and assuming is not a https site, will probably be a router problem, check your MTU/RWIN values. This happens often when you own a D-Link router as its default values are too high for EIRCOMs.

Hope this helps!!

Are you sure this is an Eircom only issue? I was in an internet cafe today and they were having similar problems 'all afternoon' according to the girl there and certainly when I was there about 6.30 pm. I didnt check today but the last time I did check on who their isp was it was BT.

I honestly doubt its a problem with the ISP, I mean, if it is a routing problem I am sure that EIRCOMs NMC will be aware of it by now. If you said you were having problems at the internet cafe could be just an internal issue.

But you never know!! I have seen worst!

The problems were similar - boards was available - bbc coming and going etc etc.

Well if at the end its a problem at EIRCOM side then it could be that one of their BAS is not correctly configured or is not working properly. Anyway there is no way of knowing

h2s

I had a quick sniff around at sites giving trouble; two routers 83.71.112.(128 & 253) appear to be one bottleneckin the loop. Also one or two esat routers.

Further anything routed through the UK e.g. through sprintlink or level 3 is suffering, this includes some irish site such as Komplett and Marx Computers.

BBC is working fine as it routes directly from one of the Eircom routers mentioned above.

Mind you this is from where I am in Kildare

Not here it's not.

I did the detailed explanation of what was broken last week (no, it's not the bloody DNS servers, they've got at least one broken router -- *again*). It's someone else's turn.

Currently I'm in the bizarre position of being able to see my own server in Texas, but only on one of its IP addresses. The one-number-away alternate address is blackholing inside the Eircrap network, apparently home to People With Degrees In Not Sucking At This.

Me, I've only got a ton of practical experience, but I know what a corrupted routing table feels like.

Muppets.

For me its fine

what happens when you trace those ips?????

Have you try connecting through a different BRAS?

b-ras1.dbn.dublin.eircom.net. Are the rest of the people connecting thru the same one?

marchanlon

For me its fine

Probably because you're not on Eircom.

I am on the same b-ras but the router with the fault is a border router for Eircom so in theory it shouldn't matter which b-ras you're on. Interestingly, some traffic is going through the router without a fault (next hop, 213.248.75.53) while most deadends on 83.71.112.202 - so looks like it's an interface or routing table issue as opposed to the router being dead.

It wouldn't be so bad if Eircom didn't just bury their head in the sand and pretend there's no problem. Hours later and still no service announcement.

Well lets just hope they realize soon, strange that at the NMC they havent already.

Never had a problem with Eircoms connection until last month when gmail and google started going down. (on each other!)

It's also affecting some traffic from the Government network - our connection out to srp.eu.blackberry.net isn't getting beyond 83.71.112.202 whilst from my own BT connection all is fine.

I wonder if there's any chance that the attack on the net on the 6th of this month could be causing some of these problems..

http://news.bbc.co.uk/2/hi/technology/6338261.stm


Hackers attack heart of the net

Icann was one of the organisations targeted in the attack
Hackers have attempted to topple key parts of the internet's backbone, in one of the most significant attacks of recent years.

The target was servers that help to direct global internet traffic.

In the early hours of Tuesday three key servers were hit by a barrage of data in what is known as a distributed denial-of-service attack.

There is no evidence so far of damage, which experts are saying is testament to the robust nature of the internet.

Websites unreachable

The so-called root servers involved in the attack act as a kind of global address book for the internet by translating website name information into IP addresses to enable computers to visit particular sites.

The servers involved were each operated by a separate body - the US Defense Department, the net's oversight body ICANN (Internet Corporation for Assigned Names and Numbers) and UltraDNS, which manages traffic for websites ending in "org" and some other suffixes.

"Last night we were seeing attacks which lasted for a couple of hours. There were probably hundreds of root server operators co-operating around the globe to make sure that the average user wouldn't notice," said Paul Levins, executive officer of Icann.

The fact that the attack remained invisible to users is being hailed as a success.

"The most interesting element of this concerted attack is that the system demonstrated the benefits of being dispersed and interoperable. There was no one point of failure," said Mr Levins.

The type of attack favoured in this case involves floods of data being sent to a machine in an effort to knock it over.

"A denial-of-service attack is a bit like fourteen fat men trying to get into an elevator - nothing can move," explained Graham Cluley, senior consultant at security firm Sophos.

If a part of the DNS system went down it would mean websites could be unreachable and e-mail undeliverable.

Research last year suggested that holes in the net's addressing system could leave 85% of the net vulnerable to take over if hackers combined simple attacks with denial-of-service attacks.

Mischief or money?

The fact that the attack remained invisible to users will be seen as evidence that the heart of the net can be kept healthy.

It was, said Mr Levin, too early to analyse exactly what happened or why; although there is speculation that zombie computers - the machines of innocent users which are recruited by hackers - were involved in the attack.

Whether the motive was mischief or money - in the form of blackmail - remains to be seen but Mr Cluley believes it is more likely to be the former.

"If money is involved there is a trail for investigators to follow. Attacking a target like this is just asking for trouble - like letting a huge bomb off in a building," he said.

parsi

We have just been informed that the issue was with eircomnet peering in London and that all is ok now. Certainly our BB traffic is back again.

still the same problems here, perhaps a list of bad sites should be compiled. anything is better than waiting for a response from eircom tech support.

I've been arguing with eircom tech support for 15 months and I still haven't been connected properly... And if one more tech guy tells me it's a problem with my laptop, I'm probably gonna throw my laptop at him. Three different computers having problems - I think it's safe to say it's Eircom and their crap service.

Actually, where are the eircom offices?... I'm totally gonna go there and yell really loudly at someone...
