I've been having problems with my websites today - none were accessible. I've been told by my host:
"The problem is that the connectivity routes between USA & Europe were changed recently and the separate routers must rearrange the routing tables and to announce between them their own networks. This will take some time and in this period, unfortunately, your website will not be accessible from some of the internet service providers in Europe.
Unfortunately, we can't give you ETA of the resolution, as the issue is on internetional level and your websites are affected along with thousands others around the Internet."
Does anyone know anything about this? How long are we talking about? Hours, days...months (eek). Most of the people visiting my sites will be from Europe.
Any info appreciated.
There is so much bandwidth over the Atlantic via so many routes that those words are not quite right as-is IMHO.
I would guess that a major routing change, eg due to a bigcable failure, would typically take of the order of 30 minutes to propagate via BGP to virtually everywhere on the planet.
And I see nothing very exciting at, for example:
[internettrafficreport.com...]
though there are a couple of interesting lumps in packet loss for Europe...
It msay be worth checking out if your host, or their upstream ISP (eg Cogent), had any major falling out with peering partners in the last day or so.

Just ask your host, eg how close is the problem to them and their upstream ISPs?
I guess it must be fairly close if you have no connectivity as opposed to poor/slow connectivity.
Also, check your own ISP, ie how you personally connect to the Net.
Routing issues can be very obscure...
