We received the following email today from our upstream (in India):

Our transit traffic partners have reported multiple sub-sea cable damages on the Atlantic route towards Europe and US east coast. Users might face additional latency and occasional packet loss towards these destinations.

Our partners are working with relevant authorities and cable sea companies for restoration and will take few days to address it. We will inform as soon as this is resolved. Inconvenience caused is highly regretted.

I've read about cable cuts due to the Tonga volcanic eruption, but the above as "multiple cable damages" is mentioned as in the Atlantic. Does anyone know more about this? A news search for "cable cuts" didn't bring up anything aside from the Tonga story.

Hi Anurag,

We have capacity on EIG cable (via Airtel) between Mumbai and London (FULL EIG PATH) and we dont have any issue at the moment.

This is an optical unprotected service, so we are not quite at the mercy of their "tuning" but on the wdm gear and physical path. Our end to end max rtt is circa 130ms (for the full EIG segment London to Mumbai)

Over the last months here is the history of downtimes:

March 2022 - aprox 4h down: Card failure (in UK) February 2022 - 100% uptime January 2022 - 100% uptime December 2021 - 100% uptime

We had a lot of downtime on EIG in November 2021 and August 2021 due to multiple issues from the cable system itself.

On the other hand we have services between Portugal, Spain, France, United Kingdom to USA and Latam on multiple cable systems and we never felt any issue on Atlantic Paths crossing the atlantic over this period of time, so i believe those reported issues are mostly on cables facing East and on Middle East/Mediterranic region. I remember one issue we had in the past with EIG was between Sesimbra Portugal and Gibraltar on EIG cable and they took like 2 weeks to fix it.

Hope it helps.

Hello,

Does anyone has an update on this? I see routing towards Airtel's own originated IPs is mostly direct but many of downstream are being routed via EU > US > Singapore path. Wondering if anyone if you got an estimated time on the cable fixes. Tata Comm did seem to have impact earlier but fixed a while ago.

Thanks.

Hi Hitesh

Thanks for that info. Did you receive that from telcos? The reason I ask that is because I still see quite a bit of AS94948 downstream getting routed via US/Singapore instead of EU -> India directly.
