Updates to follow as more information becomes available.


Updates:

  • 00:50 CT: This outage is currently affecting hosts in our DFW1 data center and primarily affects our Kerio Connect Hosting. We are investigating the issue now.
  • 01:15 CT:Our data center provider has acknowledged that the problem is in their systems. Here is their statement:
    • On 25 January 2016, at 23:15 CST, a planned maintenance began to impact some customers hosted within the DFW2 data center. Engineers are engaged and working to resolve the issue. During this time, a portion of customers may experience packet loss, latency, or failed connections when accessing their systems.
  • 02:20 CT:Our data center provider has reported that the problem has now been resolved, but, they have requested that we wait another 15 - 20 minutes before bringing our services back online. Here is their report:
    • From 25 January 2016, at 23:15 CST, to 26 January 2016, at 01:20 CST, We experienced a networking issue within the DFW2 data center during a maintenance. Engineers found that an aggregate router was experiencing high CPU utilization and causing internal connectivity issues. Teams worked to disable all port channels on the affected router, and bring them up individually to ensure the connection was up and stable. During the time of impact, a small portion of customers may have experienced inabilities to access their instances. If you have any further questions or concerns, please reach out to a member of your support team.
  • 02:45 CT:Our services in DFW are now back online. Please contact us if you continue to experience any problems.

We appreciate your patience during this work and welcome any feedback. Thank you for being a ETRN customer. Please contact us if you have any questions.

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.
