Wait... How many requests from "link"? Is that in scientific notation???
Yes indeed it is, so, it's a lot.
If you are getting so many hits from a bot that the # of hits must be listed in scientific notation, that's likely your problem...
I use Hostgator. All your logs are available on cPanel. Even up-to-the-minute.
I would download the current log & see if I could identify:
- the IP range of the culprit
- the activities the culprit is doing
When doing this, I sometimes load the logs directly into Excel for analysis.
And block the culprit, either by IP range or by user-agent if you can find a good identifier in there.
Over the years, I have had occasional issues with bots & crawls. I have a few agents blocked in my .htaccess file.
EDIT: Your logs are found in cPanel, under Metrics, Raw Access. Awstats helps if the culprit has been around long enough to be included in those stats.
