Paul Bunyan and CNS (and I suspect the others mentioned above) have dropped their BGP sessions so customers won't see an interruption when the switch change happens this morning.

Re: MICE Traffic Drops

I shut down BGP last night so when they replace the switch today it will not drop calls mid conversation. I plan on turning it back up after the switch is replaced, and I have added the new IP addresses, and moved the old ones to be secondary on my interface From: MICE Discuss [mailto:MICE-DISCUSS@LISTS.IPHOUSE.NET] On Behalf Of Justin Krejci Sent: Thursday, August 30, 2012 10:00 AM To: MICE-DISCUSS(a)LISTS.IPHOUSE.NET Subject: [MICE-DISCUSS] MICE Traffic Drops After noticing we hit over 3gig now I observed SDN, Visi, TDS, and MNVoIP all have their traffic rates drop off to basically nothing and not all at the same time.

MICE Traffic Drops

by Justin Krejci

After noticing we hit over 3gig now I observed SDN, Visi, TDS, and MNVoIP all have their traffic rates drop off to basically nothing and not all at the same time. I know our TDS bilateral BGP session is down as well. Is there something going on with the switch or is it just a coincidence several folks are doing things on their networks on the same day? ######################################################################## To unsubscribe from the MICE-DISCUSS list, click the following link: http://lists.iphouse.net/cgi-bin/wa?SUBED1=MICE-DISCUSS&A=1

To clarify, I do still recommend that people add the new addresses to their interfaces during the swap.

Did I miss a message someplace? I don't see any messages that announced the switch swap date was formalized. I would also recommend that major work such as this be announced on the MICE-ANNOUNCE list as some do not subscribe to the more active MICE-DISCUSS list.
