subject [outages] Google Issue


We've been noticing issues for the past hour accessing Google's sites. Sluggish responses mostly.

Other sites are fine. We connect through Level3 and Bell Canada.


Googleは既に主要インフラと化していますね。
NANOGでも同様に熱い話題になっているようです。

There's a ton of chatter about it on the NANOG list now.

Apparently there were some issues with a major AT&T route.

SBC Issues were also reported, this was all about an hour ago.

subject [outages] Visualizing and confirming network anomalies - Newsight


[Apologies to those on NANOG who already saw this. Given the recent
discussion on this mailing list, it seemed appropriate to cross-post
it here.]

Hi folks,

We've just released a new tool that allows you to see network problems
from end-user machines, currently BitTorrent users. (Think of this as
putting P2P traffic to good use.) The interface that we've provided is
still very beta, but we'd appreciate any (constructive) feedback.

A little more detail: we've deployed software called NEWS (network
early warning system) that uses P2P users' natural traffic to detect
sudden, unexpected drops in network performance -- this allows our 25k
BitTorrent users to corroborate network problems with each other. Our
tool, called Newsight, lets you see summaries of their reported
network anomalies.

You can browse a timeline of anomalies grouped by country, AS or
prefix. You can also confirm known network problems, helping to create
a public database of outages and their explanations.

You can play with Newsight here:

Cheers,
Dave (on behalf of the Aqualab research group)

Shane -

I'm currently talking with few individuals (coders - volunteers)
regarding building 'outages database' w/ e-mail/RSS update. This way we
don't require members to log into a web service to check status.

I want to be absolutely clear, outages database similar to the mailing
list is not to hold ANYONE accountable for an outage, its merely
reporting on them and their status. This outages database will be for
documented outages only.

Unfortunately I don't know when this tool will be ready to use / test
since these volunteers have full time jobs and having them to commit for
a certain date is bit of a challenge but hopefully we'll work through it.

Then again, I welcome donation whatever free time people can offer
(coding wise) towards this project.

If interested, please contact me directly and we can discuss off-line.


regards,
/virendra

Anyone have any details on this “miss-configuration” that caused a 5 hour outage from Qwest in northern Colorado?



I’ve heard 3 stories now, one says fiber cut, one says a miss-configuration and the final person said it was a hardware failure.


コロラド北部にてQwestの5時間にわたるネットワーク障害について3人から異なる情報を聞いた。
・ファイバー切断
・設定ミス
・機器故障
誰か詳細情報持ってる？というメール。
これほどまでに錯綜している障害情報もなかなかない。
#設定ミスで5時間不通というのは考えにくい気がするけれど。
#主経路及び冗長経路ラインをShutdownしてしまって、現地駆けつけが必要だった、とすると・・・？

Just dropping a note that there is a fiber cut in the SF area (I have a
metro line down). AboveNet is reporting issues and I've heard unconfirmed
reports that ATT and VZW are affected as well.

Rgs,

サンフランシスコ地域で回線障害が発生の模様。
続報が入ってきています。

Yup. Abovenet fiber between 200 Paul SFO and 11 Great Oaks SJC is currently
out of commission.


200 Paul Ave is seeing several carriers down. I am also in Santa Cruz and cannot make or receive long distance calls on my land lines. Unconfirmed reports of Caltrain cut.


Confirmed VZW & ATT;

Rather widespread "general telco" outage, the county has deployed
extra patrol units in the south bay to compensate for not being able
to call 911.

Third video link in shows repairs underway.

緊急電話も使えない状態だった模様。


Additional news stories reporting second fiber cut on Sprint fiber
in San Carlos, between San Francisco and San Jose, the SF Gate article above
was updated at 12:20pm with that information.

San Jose cut at around 1:30am, San Carlos around 3:30am.

OTDR readings were taken by AT&T West and a cut was located 1600 ft from
the San Jose, CA central office. AT&T West technicians are onsite
working to isolate the exact location of the cut. There are 4 cables
impacted. AT&T Mobility has 61 GSM and 45 co-located UMTS sites out of
service off of Santa Clara Base Station Controllers 15 & 23, and Santa
Clara Radio Network Controller 4. E911 has 52 Location Measuring Units
down. The AT&T West Santa Cruz 11 central office (41,803 ATNs) is
experiencing an SS7 isolation and the San Martin central office (11,904
ATNs) lost it's umbilical and is isolated at this time. The Bailey
remote site (4,973 ATNs) is also isolated. Scott's Valley has 3 out of 4
SS7 links down. The Santa Cruz 01, Aptos, Scott's Valley, Felton,
Boulder Creek, Ben Lomand, San Jose 11, San Jose 13, San Jose 21 central
offices have trunks impacted such that all lines are busy and incoming
calls are receiving trouble messages. The Santa Cruz County SO (178,040
ATNs), Scott's Valley PD (12,007 ATNs) and the UC Santa Cruz PD (14,909
ATNs) are all without ALI at this time. The Gilroy PD PSAP and the
Morgan Hill PD and CDF have been rerouted with ALI/ANI. The Felton CDF
has not been rerouted. There are 17 DSLAMS and 4 ATMS out of service
impacting DSL service. There are 3 SMDI Links down impacting voicemail
service. Verizon's Morgan Hill and Gilroy central offices are currently
isolated. There have been 224,865 blocked calls.

こういう時はOTDRが大活躍。

Have a client with a main link down in Asia. Their update from Verizon Singapore claims there is an undersea cable link down (maybe a cable cut? Not sure) between Taiwan and Hong Kong, and does not have an ETA at this time.
