I both frustrated and confused by three bizaar Comcast outages in the past week – one last week, one earlier today, and one ongoing – all corresponding to major nationwide outages according to DownDetector, so I doubt that it's just me.
The first time I noticed that some sites still worked, while others did not – I figured it was a DNS issue on their end (no major DNS server reachable, even by IP, and downdector showed a spike in outages nationwide), but it was late at night so I just switched to my cellphone hotspot, finished what I needed to do and went to bed.
Fastforward to today – same thign happens midday – some sights worked, others didn't, downdetector shows a spike in outage reports. However I needed to get work done, so after briefly investigating it I just turned on my phone's hotspot and got back to work. Eventually the internet came back up and all sites were reachable again, only for it to go down again this evening. Since I now have time I tried to investigate further and lookup the IP for a non-working site andafter confirming it worked from my phone's internet, tried the IP directly over my comcast connection to no avail :frown:.
At this point it's clearly not DNS, but it's been a while since I've messed with the finer details of IP networking, so I'm at a loss as to what's going on but it's starting to get annoying.
Thus I'm putting this out here to see
1) If anyone else is having similar problems?
and
2) Has anyone found a workaround other than switching to cell data/a backup ISP?
For the record the following sites work for me:
wikipedia.com, netflix.com, amazon.com
The following sites have not:
homedepot.com, reddit.com, ebay.com
Another post mentioned netflix working as well, while other sites did not – not sure if it the same issue: https://www.reddit.com/r/Comcast_Xfinity/comments/1vmxp80/comment/p3d5dg1
