Service Status

For use by Gigler Support to update customers of outages and maintenance work

[EddieVH]

Is DHCP / routing working as normal? I can't get an IP address. Inbound traceroutes to the old IP were showing that packets were stopping at a C4L router, although are now making it to welcome.to.gigler.co.uk

I left a phone message at about 0845, but I've heard nothing back. If you have an issue (and it looks like you do) it would be *very* helpful if you could tweet / post here about it, to save customer's frustration.

Thanks

PLEASE update your 'Service Staus' page. I've been off for the second time in a week. Frustrating not knowing likely length of outage! Been off since 17:17. Fibre is connected (lights on) but no internet.

*** Update ***

Dear Customers,

Please be informed that this maintenance has now been completed. If you are
currently experiencing issues please do call our out of hours support line.

----------



Dear Customers,

C4L have today finalised traffic testing and concluded that the additional
network capacity is stable and qualifies for final stage configuration. C4L are
now announcing the final planned maintenance in this emergency NOC
notification:

Start: 2014-02-16 at 09:00 UTC

Finish: 2014-02-16 at 13:00 UTC

Maintenance Impact Duration: 4 Hours. During this window, C4L will be
separating layer 2 and layer 3 services. Current layer 2 routes will remain
unchanged causing no expected interruption to service. Layer 3 traffic will
experience route redirection but will not reconverge causing no expected
disruption.

C4L will be implementing controlled changes on individual core locations over a
set time frame such that monitoring polling will include a full sampling period
following each change. This methodology allows engineers to verify that each
stage is stable before works on the next stage proceeds.

Please be aware that this will be an **At Risk** maintenance type, however as
detailed in this announcement, C4L do not expect service interruption.

Affected Services: Layer 2 and layer 3 connectivity.

Rollback Plan: In the event of technical complications, change costs will be
returned to the original current holding values removing the new capacity and
reverting services back to the existing C4L network.

Normal out-of-hours procedure will be operational and our engineers are
available should any customers require assistance:

packet analysis and performance testing tomorrow. C4L will publish a further
announcement to this post after tomorrow's results are concluded and reviewed.

———————————————————————-

Dear Customers,

Preliminary investigations show a successful deployment of layer 1 devices and
interconnecting switch configurations.

C4L will be monitoring events throughout the day and plan to publish a further
announcement to this post this afternoon.

———————————————————————-

Dear Customers,

The works at the weekend uncovered some hardware issues which necessitates
further works. Additional hardware will be installed at the core locations to
complete our capacity increase.

Start: 2014-02-13 at 02:00 UTC

Finish: 2014-02-13 at 06:00 UTC

Maintenance Impact Duration: 4 Hours. Please be aware that services are **At
Risk** and customers taking transit services and layer two interconnects may
experience a short period of packet loss.

Affected Services: IP Transit, Layer Two Interconnects

provide an improved level of stability in the meantime.

Please be aware that this will be an **At Risk** maintenance type, and
customers taking transit services and layer two interconnects may experience a
short period of packet loss during the maintenance.

Start: 2014-02-09 at 02:00 UTC

Connectivity Issue – 06/03/14
March 6th, 2014

***Update 09:57***

Dear customers,

Service disruption has improved though is still present in some locations. C4L engineers, in collaboration with upstream providers are mitigating against the source of the traffic and are working towards a resolution.

Further updates will follow.

____________________________

***Update 09:42***

Dear customers,

Efforts are still ongoing to mitigate the impact of the increase in incoming traffic. C4L engineers are working with upstream providers and are working on measures to restore normal levels of service.

Further updates will follow.

____________________________

***Update 09:21***

Dear customers,

We are now taking steps to mitigate the increase in traffic by controlling our incoming peers. Further updates will follow shortly.

____________________________

Dear Customers,

C4L monitoring systems have reported increased volumes of traffic traversing through some areas of our network. Some customers may be experiencing packet loss and increased latency. Furthermore, our telephone system is suffering from poor quality meaning that two-way conversation is being affected. Our network team is investigating the cause of the problem and regular updates will be posted to this site.

In the meantime, please accept our apologies for the disruption.

Apologies for any inconvenience experienced.

Extremely poor speeds once again - seems to be the norm recently.. Very erratic and inconsistent. Did a speedtest tonight and was down to 45mbs rather than the usual 650+ !!

Come on Gigler - the way its going at the moment I might as well return to Virgin's 100mb, as at least its consistent!!!

[handyt]

Are there currently problems in Bournemouth? Service is stable for 30 mins or so then ONT gets red light on optical connection. Turning off for 15+ minutes seems to let it recover for a while and then it dies again.

Please Please Please update your Service Status when you have a fault. It's the first place people will look and will save a lot of frustrated calls on your UNANSWERED voicemail. You have put the following comment on your twitter account but not here. Makes no sense. Thank you.

Gigler @GiglerUK · 17s

Services Restored! We're back up and running now. Sorry if you were affected and thanks for your patience

Gigler @GiglerUK · 50m

Some customers are experiencing connection problems. Our engineers are working on it now. Sorry for any inconvenience

[BourneWeb]

FYI, there are issues at c4l county gates.

Emergency work will commence at 1330.

If you'd like more detailed information of the exact issue please ask

[Jammyb]

Still down for me in Winton BH9.

Any ETA on reconnection?

BH10 too. Back on now but a 2 and 3 hour outage overnight (as well as 8 to 10 yesterday morning).

Hopefully they got to the root of the problem. Now we know that all of Gigler internet access is through C$L (Connections 4 London?) at Frizell roundabout. If they have a problem.... everyone's out.

[BourneWeb]

Hello
Gigler provide the local connections to homes in the area.

In turn, they get their back bone connection to the internet from county gates, c4l. C4l own a number of data centres with transit routes between them all.

In fairness, c4l are very quick with updates to problems with their network. Yesterday problems were identified at a number of their data centres. It became clear that there were also problems at county gates.

They initially scheduled emergency works to deal with these problems around 1330 yesterday. This was a temporary solution with more works scheduled for during the night. During the night a number of devices had to go off line and a number of other devices rebooted.

All came back online again at 0653.

Maybe this helps others understand what is going on.

Just to add, this is how all ISPs operate and every part of the internet relies on other transit routes and providers to supply a service. Every network connected to another = internet. Generally c4l have very good redundancy should a route fail.

[venuetech]

Thank you for that info.

We are very lucky in north Bournemouth to have such a fast connection and faults are inevitable from time to time. As a subscriber it helps a lot if the status update is current as we then know that you are aware of a problem.

Keep up the good work.

[BourneWeb]

Hey, glad it helps; but I'm just a regular geek with an 'in' at c4l. It might be nice if Gigler also gave a comprehensive update; just for those that are interested. Then again, maybe they work on the fact that most people wouldn't notice intermittent down time.

[localmandave]

Hi Support,

BH11 9BN and currently have no connection, this may be as Virgin Media are laying their connection down here and really hope they have not cut through the line yet again, please can you assist?

Many thanks,

The Gigler Team.
