How Query collects its data
Query reads the outage, earthquake, weather and duty pharmacy lists that agencies publish openly on their own websites, at regular intervals. It converts them into one format and shows every record with its source and time. It adds no forecasts of its own and no user reports.
Which sources
Distribution companies for electricity, metropolitan water utilities and city municipalities for water, Gazdaş Trakya for natural gas and Türksat Kablonet for internet. AFAD and USGS for earthquakes, and the Norwegian Meteorological Institute (MET Norway) for weather. For duty pharmacies, İzmir Metropolitan Municipality's open data and the pharmacists' chambers' pages.
Each source's name, provinces and status are on the data sources page.
How often
It depends on the source. AFAD is read every minute. Most power and water sources are read every 5 minutes to 1 hour; a few companies that rarely change their list are read twice a day. Weather forecasts for 81 province centres and 973 district centres are refreshed on a 6-hour cycle.
Every page shows the time of the last successful check. If a utility's site cannot be reached, the old data is not deleted; it is shown with a warning.
Sources we do not read
We do not read some agencies' data:
- The outage lookup requires a CAPTCHA: Başkent EDAŞ (Ankara and 6 provinces), AYEDAŞ (Istanbul's Asian side), Toroslar EDAŞ (Adana, Mersin and 4 provinces).
- Behind bot protection: TREDAŞ (Edirne, Kırklareli, Tekirdağ).
- Closed to crawlers in robots.txt: Aras EDAŞ, Türk Telekom.
- Requires an access token: İSKİ.
- Terms of use forbid republishing: MEDAŞ, Çoruh EDAŞ, Fırat EDAŞ. They will be connected if permission is granted.
In these areas the page says "no official source connected" and points to the utility's own lookup page and fault line. It never shows made-up or estimated data.
The path of a record
Every record read is converted into the same format: type (planned or fault), start, end, district, neighbourhoods, cause. Times are stored in Turkish time. Province and district names are matched exactly against Query's place list; a name that does not match is not guessed, and the record is shown at province level.
An outage that drops off the utility's list is closed. Personal fields such as employee names are not stored. The full rules are on the methodology page.
Where it can be wrong
- If the utility updates its list late, Query shows it late.
- The end time of a fault is the utility's estimate.
- Some water utilities publish outages as announcement text instead of a table. Query tries to extract the time and place from the text; if it cannot, it shows the announcement with its title and link.
