Elevated connection errors in us-east-1
Resolved - us-east-1 is reenabled and the service is operating normally.
The root cause has been confirmed to be a defective Network Load Balancer that was causing a small fraction of connection attempts in the region to fail. We are awaiting a postmortem from AWS on the issue, and will publish our own postmortem here once we have that.
Oct 26, 11:45 UTC
Update - us-east-1 remains disabled. All traffic is being routed to other regions so there is no ongoing impact on service.
Oct 25, 22:55 UTC
Monitoring - Traffic is no longer being routed to us-east-1, but instead to us-east-2 and us-west-1.
We are continuing to investigate the root cause of the networking issue in us-east-1.
Oct 25, 21:33 UTC
Investigating - We are seeing an elevated rate of connection errors in the us-east-1 region, seemingly as a result of a partial loadbalancer failure. We are disabling the region so traffic will be routed to other US sites.

issue with rewind=1 and persist-last in some situations
Resolved - Between about 14:00 UTC on the 20th and 17:00 on the 21st, on channels with the persist last message (https://ably.com/docs/channels#rules) channel rule enabled, attachments with `rewind=1` in situations where the most recent message was published over two minutes ago but still somewhat recently (and where the channel has been continuously active in a given region since the message was published) may not have had that rewound message correctly delivered to the attaching client. We apologise to anyone whose application was affected by this.
