Start time: 3:00 PM central 6/27/2014
Maintenance Duration: ~15 minutes
Impact: Brief disruption in traffic flows

Vendor statement:
"Beginning at 15:00 CST on July 8th, Network engineers will perform a combined maintenance to upgrade the management module and router firmware revision on our edge border router. The new
router firmware will be staged before hand on the new management module, along with the current configuration to ensure minimal disruption and downtime for all customers. Customers will notice a brief disruption to traffic flows during the swap-out of the management module, and possible transient forwarding loops during BGP re-convergence. Engineers will be following a pre-planned maintenance script to minimize impact to our customers service. We apologize for any inconvenience this maintenance may cause, and appreciate our customers understanding as we continue to build additional capacity and redundancy into our network infrastructure.

Our network operations engineers will closely monitor the system during this maintenance window and will do everything possible to minimize any inconvenience to you. Our system should automatically fail-over to other circuits during this time. If you have any problems with your services after this time, or if you have any questions regarding the maintenance at any point, please contact us.

We appreciate your patience during this work and welcome any feedback. Thank you for being a ETRN customer.

We Answer Your Questions: FAQ

Q: What is the maximum e-mail attachment size?

A: The ETRN.com e-mail servers do not limit the size of individual e-mail attachments. The ETRN.com e-mail servers do impose a 400 MB maximum total message size limit. Individual customers can choose a smaller message size limit. We can also customize the handling of "over-sized" e-mails. Please contact us to discuss your specific needs. A couple of important facts:

1. Attachments are typically encoded in what is called Base64[1]. As a result, the actual length of MIME-compliant Base64-encoded binary data is usually about 137% of the original file size.

2. E-mails often contain both plain text and HTML components. This also increases the overall size of the e-mail.
