As a reminder - I'm still planning to do the MICE exchange upgrade tomorrow morning between 5am and 7am CDT. I'll be shutting down the route server ahead of time, but as we talked about those of you with bilateral sessions or sensitive SLAs may want to take action ahead of time. I'll send a note out when everything is complete.

Juniper believes we're encountering a known bug that has been fixed in later software releases. Here's the bug description for people with Juniper support ids, as we'd suspected it deals with L2 database MAC learning/maintaining: https://prsearch.juniper.net/InfoCenter/index?page=prcontent&id=PR695200 The upgrade will require a short interruption in exchange traffic. We're currently planning on performing the upgrade next week on Wednesday morning - July 29th between 5am and 7am, that should be the low point in our daily traffic volume. Can someone forward this to the Announce list?
