Scheduled Downtime – 9:00 PM Thursday, March 3rd
FIHN will be doing a service impacting network reconfiguration at 9:00 PM on Thursday, March 3rd, 2011 to prepare for BGP setup and additional uplink. This maintenance will take the entire network offline for up to 10 minutes while a change is made at my switch and at my providers end to accommodate for the change.
These changes will make it possible for me to fail over the network to a second provider in case of an issue with the primary. A BGP fail over in this scenario can usually be detected within a matter of minutes and the route for the failing provider then taken out of the routing table to force traffic out a different provider. The second provider has yet to be determined.
If you have any questions about this maintenance please contact me by email or phone. Thanks!
Update: Maintenance completed at 9:40 PM. Thanks to Di @ EGN for setting up a second /30 to transfer BGP setup without downtime!
Upstream Router Maintenance – Thursday, Dec. 23rd @ 7:00PM
I am passing along this (rather short notice) router maintenance that I received. This maintenance is likely to affect everyone in the 72.13.92 and 68.68.98 subnets.
————————————
Start time: 7:00PM PST 12/23/10
End time: 7:30PM PST 12/23/10
Work order number: SJC2-MLX01-12232010
Expected Outage/Downtime: 5 or less minutes
Energy Group Networks customers receiving service in our San Jose data centers will be affected by this maintenance. Customers should expect up to a five minutes service interruption during the maintenance window. Customers may also see some BGP reconvergence during the maintenance window.
The reason for this outage is to perform a necessary firmware update to address an bug discovered with current firmware that occurs after 624 days of uptime. This update will also add a few more IPv6 enhancements previously not available.
————————————
Sorry for the late notice. One of my goals in 2011 is to setup a BGP session with multiple providers to better control maintenance windows like this by shifting traffic on the fly. As always, please let me know of any questions. Thank you!

Upstream Router Reload
Hi Everyone,
I have learned that my upstream provider is planning to do a router upgrade in the data center between 6:00AM and 9:00AM on Saturday the 16th, August 2008.
Please be aware that the network will be down for about 5 – 10 minutes while the router is reloaded. I will be assisting with the router upgrade and should anything go wrong I will be on hand and will be able to give details of any longer than expected down time.
If you have any questions feel free to let me know. Thanks!
Major Software Updates To womp.fihn.net
I have performed some software updates on the womp.fihn.net hosting server. Most of the updates apply to the email system spam detection and blacklists. If you notice anything strange happening with your hosting account please contact me immediately.
Thanks and have a great day!
