A network issue is happening. Applications may be unreachable.
Console is partly down.
Some apis are down.
EDIT 18:20 UTC: Here is the history and context of the network issue:
At 17:25, a maintenance on a component of a redundant network link caused one of the underlying links to fail. For reasons unknown at this time, the failing link was elected and about 30% of packets were lost until 17:29.
At 17:30, the network engineer decided to revert the change; this caused additional loss for about 30 seconds. Network was back to normal at 17:31.
