CenturyLink service interruption January 31

CenturyLink has informed us of a planned interruption of service of between one and three hours to our entire network, sometime between midnight and 6:00 AM on the morning of Thursday, January 31. The interruption is for “scheduled maintenance to upgrade routing engines in order to improve network reliability and to prevent future service interruptions to customer services.”

Occasionally, CenturyLink may reschedule this interruption one or more times before it actually occurs. We will report any changes to the scheduled date and time as notice is received.

CenturyLink service interruption January 8

CenturyLink has informed us of a possible interruption of service of between one and three hours to our entire network, sometime between midnight and 6:00 AM on the morning of Tuesday, January 8. The interruption is for “scheduled maintenance to upgrade equipment in order to add network capacity and prevent future service interruptions to customer services.”

This far in advance of the scheduled date, there is a good chance that CenturyLink may reschedule this interruption one or more times before it actually occurs. We will report any changes to the scheduled date and time as notice is received.

Cutover still pending

This morning’s trunk cutover failed to take place, with CenturyLink making the attempt to switch circuits but ultimately delivering no traffic. Next-tier engineers at CenturyLink are scheduled to be diagnosing the issue, and we’ll be setting up a new cutover time once they inform us they have the problem figured out.

Trunk cutover Thursday AM

Tomorrow morning (Thursday, August 23), between 6:00 and 7:30 AM, CenturyLink will be moving our gateway service (our trunk connection to the greater Internet) onto a different fiber link. We expect an outage blip of about 15-30 seconds during that time period, barring complications. If complications occur, we will revert to the original fiber link as expeditiously as possible and reschedule the cutover. We regret the short notice, but we received this scheduling information only this morning.

CenturyLink service interruption July 19

CenturyLink has informed us that they intend to interrupt service to our entire network temporarily between 3:00 and 6:00 AM on July 19. The interruption is to perform maintenance on one of their routers in Phoenix that serves a large number of customers in our area of the state. The interruption may or may not require the entire time period; service should resume in any case no later than 6:00 AM.

This far in advance of the scheduled date, there is a good chance that CenturyLink may reschedule this interruption one or more times before it actually occurs. We will report any changes to the scheduled date and time as notice is received.

CenturyLink service interruption April 1

CenturyLink has informed us that they are likely to be disconnecting our network from the greater Internet temporarily between 3:00 and 6:00 AM on April 1. The interruption is to introduce new routing equipment at their premises and migrate some of their existing traffic to reduce load and reduce the likelihood of customer service interruptions. Service should resume no later than 6:00 AM.

This far in advance of the scheduled date, there is a good chance that CenturyLink may reschedule this interruption one or more times before it actually occurs. We will report any changes to the scheduled date and time as notice is received.

Update (April 1): Upgrade was achieved cleanly between 3:50 and 4:04 this morning.
