Like many providers today, OLI helps protect client access and data with scripts that block IP numbers of computers attempting to scan all our ports, guess client logins, flood customer accounts with spam, and other activity that appears malicious.We only unblock IPs by customer request.
For example, sometimes a customer’s computer gets infected with a virus which causes their computer to launch an attack. After the customer removes the virus we can allow access again. IP netblocks of compromised networks are blocked if the problem is persistent or causing disruption to our customers’ access.Such steps prevent countless server crashes and other inconveniences to customers.
Also at certain times when incoming spam traffic reaches certain levels, OLI implements filters from Spamcop.net and/or Spamhaus.org to protect the server load levels for all users.
