Hi all,

Yes, this is the worst time. Almost the whole tech team is sole focusing
on that emergency.

We had earlier today some problems with a maintenance procedure that went
out of control. And at the moment we are facing the following issues on the
Tasking Manager that has been brought back:

- Locking of tasks is not working and throws an error message.
- Login is failing for some, not for others
- Activities of late yesterday, such as projects that have been created,
might be lost in the database, as we had to use a backup from yesterday.

We are working on solving it soon. And will report here and in our other
channels (slack, twitter.com/hotosm_tech and status.hotosm.org) more

In the meantime we can only offer alternative instances such as:

* tm3.openstreetmap.id
* tasks-assisted.hotosm.org
* tasks.teachosm.org

Please excuse the inconvenience and we will post any updates as soon as

So far an update from the infrastructure experts on what happened earlier

> *Summary:*
> Tasking Manager is now back and working. Unfortunately, many email
addresses were lost and therefore some users who login will be asked for
their email addresses again. Projects are intact and unaffected
> *So what happened?*
> During the scheduled maintenance to upgrade Tasking Manager instance, one
of our automated scripts deleted our database. This is not unexpected. But
the backup we made before deletion was deleted along with the database. In
a nutshell, we lost the production database completely, including automated
backups. We however had a separate offline backup that was taken manually
yesterday. But we had stripped email addresses from this database backup
for privacy reasons. We had to restore email addresses from another offline
backup from 10 days ago to fix it. We are now closely monitoring the DB and
the application for any problems.
> *What can you expect in the future?*
> We learned many valuable lessons from this including our approach to data
backups, performance and stability. All our experiences from the outages of
recent past have made us think about how to overhaul our approach to
optimize our infrastructure. We will work to implement processes to
mitigate performance, deployment and stability problems over the next few
weeks.  We are also working on a detailed RCA with technical details of the
We understand that this would have caused quite a bit of frustration and we
apologize for that. You can expect things to improve in the next few weeks.
