Cox website slow - or me?

I have been having many issues of late, one of which is when I log into cox.com (CHROME or FIREFOX) it seems to take a long time once I enter my credentials until I am actually logged in, and then it usually takes a long time to get to whatever destination I am looking for. Is it just me? I also have had very sporadic internet (hard wired) service. With SPEED TEST I can often see (in the same test) speeds varying from 50Mbs (and above) to less than 10 Mbs. I replaced my gateway yesterday with a new ARRIS  TG1682G so I don't think it's hardware related. I also checked all the internal house wiring and splitters yesterday while I was experiencing extremely slow service by substitution and bypass) and all that was fine (several hours wasted). Ever since the big outage last Friday my internet has been worse than usual (have had issues for years). Sometimes my neighbors have the same issues, sometimes not (their drop is from a totally different service across the street). Presently I am waiting for Tech Support to contact me back about scheduling a service call, but if things aren't broke the day the Tech comes that will serve no purpose. Any ideas? Thanx.
