Site/line: SVUH, UCD
In the last view days the signal strength on the following two links has
degraded to the point of raising concerns about link reliability:
- SVUH to UCD (primary link for SVUH)
- UCD to TCD (resilient link for UCD)
The cause of the degradation is being investigated, but as an interim
solution in order to bring the signal strength back to within the safe
range, we will temporarily remove any attenuators on the links at present.
In order to remove the attenuators, each link will have to be broken
briefly. The actual outage should be no more than a minute, but the links
should be considered at risk for the scheduled period.
SVUH will lose connectivity on their primary link during the outage, and
traffic will fall back to their resilient link.
The UCD link is a resilient link so UCD will lose only resilience during
the outage on their link.
