Hi all,

Etherpad [0], our real-time colaborative editing tool suffered an
outage due to what we only know for now was database corruption. This
was detected shortly after it happened 14:27 UTC and we (ops in charge
of the service and the database) worked to reestablish the service.

As the service continued crashing despite our efforts, we decided to
recover a database backup from 2016-06-22 01:00:01 UTC. The service is
now back up and working since 16:11 UTC, but that means that you may
have lost a day and a half of edits in the current available etherpad
[0].

I understand that that may cause a lot of inconveniences, specially
for the people at Wikimania. *We are now trying to recover more than
that*, but as the corruption could come back, or not all could be
recovered, and people need the service the plan is the following:

- Keep the current pads as is, not delete or add anything from now.
You can continue using etherpad now as usual.
- If possible, recover the last days of edits on a separate location.
See [1] for progress if you are affected.

Sorry for the inconveniences. Please, more than ever, follow the
recommendation we added at the beginning of every empty pad:
> "Keep in mind as well that there is no guarantee that a pad's contents will 
> always be available. A pad may be corrupted, deleted or similar. Please keep 
> a copy of important data somewhere else as well"
The reason for this is that wiki content has proper HA and redundancy,
etherpad does not.

Again, my most sincere apologies,
