Beginning at 11:59PM on Wednesday, August 24th, we will be carrying-out network upgrades on a portion of our core network in Southern California. Sonic enterprise SSE customers in the region will experience a 1 or 2 hour downtime as we move equipment that is essential to that particular service. All other services may notice some routing changes but should not experience any downtime.
Update(9:15PM): A latent misconfiguration causing traffic loss for many subscribers in the Southern California area was exposed around 8PM when draining transit traffic in preparation for this operation. Due to the nature of the traffic loss our network monitoring did not catch the issue immediately. We were able to restore all traffic by 9:05PM and apologize for the inconvenience. We will be taking steps to protect against this type of failure in the future.
