Occasional anomalously-high `messages.inbound.rest.messages.refused` stat when a rest publish is refused
Resolved - The fix for this has been fully rolled-out.
Oct 11, 12:20 UTC
Identified - Since Monday 7th, a REST publish that was refused by Ably's servers (for example, for being above the maximum message size) had a small probability of contributing an incorrect, anomalously high message inbound refused stat (key `messages.inbound.rest.messages.refused`) to app and account stats.

Since refused messages do not count towards a customer's chargeable message quota, this bug did not result on anyone being charged more or having their quota used up. However, in a couple of cases it did momentarily trigger a customer's account-wide instantaneous message rate limit (`messages.maxRate`), for which we apologise.

We are rolling out a fix for this currently.

Some SSE connections disconnected and reconnected every 30s
Resolved - For most of the production cluster, between 13:05 and 14:02 UTC on 2024-10-01, a small proportion of SSE connections were disconnected 30 seconds after establishing a connection. For the duration of that 30s they still worked fine, and connection resumption was working correctly, so this should not have caused any missed messages. The net effect would have been a small increase in subscribe latency about once every 30s.

Only the SSE endpoint was affected; websocket traffic (including anyone using an Ably SDK) was not.

For customers connected to ap-southeast-2 (Sydney), the duration of the effect was much longer, between 10:06 on 2024-09-30 to 14:02 on 2024-10-01.
