Re: Transition of ENSS206 (CERN) <-> CNSS35 (ANS N.Y.) to Ebone Service
The rehoming of the U.S. end of the Geneva circuit from New York to Washington, and associated changes to the routers on the ends of the circuit, is complete and appears to have been successful. The only snag is that, due to a configuration boo-boo, it was not possible to use the intended primary path through CNSS57. Routing to AS 690 has hence fallen back across MAE-East to ENSS136 (though with the native AS 1133 in use). This will be corrected in Tuesday morning's configuration run unless load on MAE-East seems excessive, in which case we'll force the configuration change through sooner. I've included a (slightly modified from yesterday) map of the situation for people who like such things.
