Dear all,
the Overpass API instance on overpass-api.de will receive in a few hours
a data rollback to 22nd Oct 2014. This means a shutdown for two to three
hours. Then it will catch up from 22nd October to recent data.
The other instances on
- http://overpass.osm.rambler.ru/cgi/
- http://api.openstreetmap.fr/oapi/
aren't affected. They will continue to deliver current data.
Recent attic data will not be available for some days. I'm sorry for the
inconvenience. However, attic data before Oct 22nd should be
consistently available also during rollback.
Details about what most likely happened:
On saturday morning I've made a software update to version 0.7.51. As
there was no change in the database format, the change went smoothly and
all indicators looked fine.
However, I've wrongly configured the dispatcher for areas to also care
on meta data. Once the areas dispatcher triggered the first update of
areas, .i.e. a few hours later, it corrupted the meta data, in
particular the *.idx files.
The processes have run with
dispatcher --osm-base --db-dir=/opt/ssd/v0.7.50/ --attic
dispatcher --areas --db-dir=/opt/ssd/v0.7.50/ --attic
They should have run with
dispatcher --osm-base --db-dir=/opt/ssd/v0.7.50/ --attic
dispatcher --areas --db-dir=/opt/ssd/v0.7.50/
At this point I would like to thank the people that have complained.
This gives me the impression that a fast and prospectous resuce attempt
is better than a lengthy investigation without meta data. Given the
wrong parameter was the cause, future software versions will be
protected about these kinds of wrong parameters to the possible extent.
I'm sorry for the service disruption.
Best regards,
Roland
