FYI, I'm an admin on a vBulletin forum on a different website and we've been getting this exact same issue -- same IP even -- for a couple days now. I thought it was a very strange coincidence that I got this same email from Parallels when we are having the same issue. Based on the IP the ISP appears to be ThePlanet.com: OrgName: ThePlanet.com Internet Services, Inc. OrgID: TPCM Address: 1333 North Stemmons Freeway Address: Suite 110 City: Dallas StateProv: TX PostalCode: 75207 Country: US ReferralServer: rwhois://rwhois.theplanet.com:4321 NetRange: 220.127.116.11 - 18.104.22.168 CIDR: 22.214.171.124/15, 126.96.36.199/16 I called them and emailed their abuse address with this info, but I haven't gotten much in the way of a response -- basically they'll look into it but cannot even guarantee a response or any action. Pretty lame -- not sure what else can be done. Maybe if someone from Parallels can also contact them they'll take a look.
