On the morning of July 18 there was a hardware failure at MAE-East that kept breaking off the BGP sessions every 2-5 minutes. This took place from about 4:00 until about 8:30 am. The report we recieved back from SURAnet was that MFS ended up simply power cycling the Netedge boxes. Sessions with all peers except ICM and one of the PSI routers were bouncing. R.
