Most of the ISP's in Malawi have been having issues since the 17th due to a severed cable in the Red Sea. Oliver

- -------------------------- I don't have a direct feedback into this disruption but from what I gather they were able to (manually) re-route traffic (alternative submarine cable and /or satellite systems) whether its slow that's a different story but having performance degradation, as opposed to complete service outage is still workable, IMO. Hopefully diversity will help minimize localized damages as the global economy (communications, education, business, entertainment, banking & commerce) continues to be dependent on undersea cables. Typically the GPS navigation suite has undersea cables well documented. I for one am interested to know how this was overlooked or maybe human error? regards, /virendra -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iF4EAREIAAYFAk9LyVkACgkQ3HuimOHfh+FZggD/a+LIEBXANdItl2NGbaTCRQsh +5/l0RvFRL3EMws8IsAA/jlV2gFGzCB1SM8pFAmKnK6sgS38tnxDFDj/4KqIUFky =40jD -----END PGP SIGNATURE-----

The ship was reported to have dropped anchor while in a restricted or prohibited area. These areas are _EXTREMELY_ well marked on charts. I can't see it being anything other than human or mechanical error: not checking if the ship is in a no-anchorage area, or the anchor chain wildcat brake _and_ the anchor chain blocking device fail simultaneously, or watch officer totally mistakes the ship's location and orders the anchor to be let go. -- Mike Andrews, W5EGO mikea@mikea.ath.cx Tired old sysadmin

One more option: engine or steering failure making dropping the hook an urgent necessity. What are the chances you'd hit a fiber-optic cable. ; - ) Greg

There's about 1/2 a dozen or so known private and government research facilities on Antarctica and I'm surprised to see no fiber end points on that continent? This can't be true.

Cost-benefit. A dozen sites, each with only 100-200 people, scattered across something a tad bigger than Europe. Even if you *land* a cable (which would be a technical challenge, as there's few places you can land it without having to contend with an ice shelf), the other 11 sites will *still* be so far away that dragging fiber to *there* will be cost-impractical. Especially the ones that are moving because they're actually on glaciers or ice shelves. But hey, if you think you can do it without going broke, go for it. ;)

Constantly shifting ice shelves and glaciers make a terrestrial cable landing very difficult to implement on Antarctica. Satellite connectivity is likely the only feasible option. There are very few places in Antarctica that are reliably ice-free enough of the time to make a viable terrestrial landing station. Getting connectivity from the landing station to other places on the continent is another matter altogether. jms

Yes. I had discussions with some of their network support folks circa 1994 -- with limited bandwidth (DS0, as I recall) and only a few hours of connectivity per day, when a satellite was over the horizon, they were very concerned about attackers clogging their link. --Steve Bellovin, https://www.cs.columbia.edu/~smb

It sounds like there were multiple cables that were lost recently. For the EASSy cable issue in the Red Sea, an ISP in Malawi stated the issues started at "09:26 on Friday 17 February". I don't know first hand if that is accurate to the minute or not. I believe this is separate from the cable off the cost of Kenya that was cut on the 25th. Oliver

Renesys published a brief writeup of the incident yesterday. We called it at 09:13 UTC on the 25th. Lots of interesting outage and transit-shift effects to see in the East African BGP data that day. We also report some shifts in latency based on active measurement, as everyone's traffic jumps onto the surviving connectivity through SEACOM.
