If they are ISP's and your computer is talking to one of their users you may want to do a thorough malware scan.
Yeah, it's crazy... that 'fastly.com' outfit has something to do with outfits that interface with social media platforms. That's a whole different market. For instance, Fastly's clients include Vimeo, BuzzFeed, New Relic,
KAYAK, Opera Software ( of which I use Opera browser), et al.
'linxtelecom.com' is a server mamagement concern and provider. I went to Kaspersky Internet Security a year ago, after being with avast! for about 6 yrs. Why?... Kaspersky and BitDefender have consistently been ranked the #1 AV for 4-5 yrs. running. BitDefender does not integrate with Opera browser, and Kaspersky does, to a degree.
I'm going to run that cmd prompt-
