IPv6 in EECS: Finally Coming Soon

by

After a long preparation, we are almost ready to begin providing IPv6 service. We originally planned to be ready by the end of August, but due to various delays we are currently about one month behind schedule. Our remaining steps are:

* complete replacement of existing border router
* request IPv6 blocks from campus
* configure IPv6 routing
* begin providing IPv6 connectivity

We anticipate that in the best case scenario we may be ready for early deployments as soon as late September, although October may be a more reasonable estimate if further complications arise.

Our plan, once the routing core has been enabled for IPv6, is to start with small deployments on our backend infrastructure networks and also for research groups which have been waiting some time for IPv6. These initial deployments will be barebones “plumbing only” and likely will not include automatic IP address assignments (DHCP/SLAAC) or name services (DNS). When those services are ready, we will begin a large-scale deployment of IPv6 to the public production networks.

If you are interested in IPv6, please take a moment to fill out the survey linked here. This will help us gauge interest and let us know who to reach out to for the initial deployments.

Network Border Maintenance, 6/20/17 7AM

by

We will be performing maintenance at the EECS network border at 7AM on Tues. June 20th. There may be a brief loss of connectivity between EECS and outside networks at this time.

If a loss of connectivity occurs, we expect it will likely last less than five minutes. In this event, the following traffic paths would be interrupted:

* EECS to campus networks
* EECS to Internet
* EECS to Millennium research

The following will not be affected:

* Traffic within EECS networks
* Millennium research connectivity to campus/Internet
* Science DMZ
* Private networks in the EECS DMZ (CESR, DETER)

“EECS” in this case refers to all wired and wireless production nets, all server and machine rooms, and all private networks not otherwise mentioned above.

Please contact help@eecs if you have any questions about this change or concerns about scheduling.

Campus Wireless Networks Unavailable, 6/7/17

by

Campus wireless networks (AirBears2, eduroam, CalVisitor) were unavailable for a period this morning due to an issue with authentication load balancers. At the direction of campus wifi admins we have reconfigured these networks to bypass the load balancers for now.

All networks are once again available for use within EECS.

Resolved as of 2017-06-07 08:50:00

Soda Aggregation Router Upgrade, 5/2/17

by

We will be performing a software upgrade of the Soda Hall aggregation router at 6:30 AM on Tuesday, May 2nd. Wired and wireless networks in Soda Hall will be unavailable for 5-10 minutes while the router reboots. BWRC will also be cut off from the outside world during this time as its uplink is dependent on this router.

The Millennium research network will not be affected.

This upgrade is being performed to resolve certain bugs in the current software version so that we can move forward with our early-stage IPV6 deployment, which is currently targeted for this summer.
