Hi,
We need to delay this switchover. We’ve made some changes to the plan that require a bit
more prep work. Follow
https://phabricator.wikimedia.org/T185225<https://urldefense.proofpoint.…
for more details.
I’ll reply with another announcement email when we set a new date.

Hi all!
If you are not an active user of the EventStreams service, you can ignore this email.
We’re in the process of
upgrading<https://urldefense.proofpoint.com/v2/url?u=https-3A__phabricat…
the backend infrastructure that powers the EventStreams service. When we switch
EventStreams to the new
infrastructure<https://urldefense.proofpoint.com/v2/url?u=https-3A__phab…COc9TxUncTy9nnNxG1E&e=>,
the ‘offsets’ AKA Last-Event-IDs will change.
Connected EventStreams SSE clients will reconnect and not be able to automatically consume
from the exact position in the stream where they left off. Instead, reconnecting clients
will begin consuming from the latest messages in the stream. This means that connected
clients will likely miss any messages that occurred during the reconnect period.
Hopefully this will be a very small number of messages, as your SSE client should
reconnect quickly.
This switch is scheduled to happen on June 5 2018, at around 17:30 UTC.
Let us know if you have any questions.
Thanks!
