Forwarding from JISC-REPOSITORIES list – we’ve been seeing this in California too, and our IRStats2 counts are through the roof for the last couple of weeks.

 

Can anyone tell me how to filter out these robots in IRStats2?  And how to clean the access file so that our irstats2 reports are not distorted by this deluge?  I assume I’d want to delete all entries with a requester_id in the table below and rerun IRstats2 setup from scratch.

 

Thanks,

Hi everyone,

 

There was a discussion, via UKCORR mailing list, on why there are exceptionally high downloads being seen this week in IRStats and what might be causing it.

 

After some investigation we have found that the unusually high downloads are down to four IP ranges:

 

IP range	Organisation	Location	No. IP addresses
103.25.156.*	Microsoft Bingbot	China	128
103.36.96.*	Microsoft Corporation	China	216
111.221.28.*	Microsoft Bingbot	China	256
202.89.235.*	Microsoft Bingbot	China	80

 

These IPs have been systematically trawling and downloading files from many UK repositories. Looking at their User Agent strings they do not declare themselves as bots but masquerade as normal users.

 

Happily, the IRUS-UK ingest has been filtering out these robotic downloads, so you won’t see a massive spike in your IRUS-UK stats.

 

We hope this is of help.

 

Best wishes

Hilary
