I'm using a small script that it's scheduled to run daily, and all it does is to scrape a site and collect the data into some CSV files. Usually, this task takes about 2300 seconds. Only this evening I observed that in the last 4 days the script only took about 20 seconds to run. After a better check, it seems that the csv files, which also contained some links that had to be scraped, are empty - so 15 months worth of data are gone. I must say that I haven't done any modification to my script lately. Do you guys have any idea what could have happened, and also, is there any chance of recovering the lost data?
