For those of you with Virgin, good luck, the merger with O2 is not based on becoming a world leader but to try and gain more services to cross sell. TEF have been trying to offload the UK O2 business forever and investment was culled in many areas during that period. I doubt the new business is going to be as well funded as it needs to be to fight the other two monsters that are shaping up.
BT, EE, PlusNet
Vodafone, Three (with the merger announcement last week)
Re the comment on DNS there are lots of alternative services available now.
There is no reason that you have to use the one provided by your ISP.
https://www.techradar.com/news/best-dns-serverI have been using Cloudflare for some time now and it's great.
Cloudflare offer an excellent free consumer service which is also a lot more private, set to 1.1.1.1 and 1.0.0.1
They also offer a curated pron/gambling filtered DNS for those who would benefit 1.1.1.3 etc
Google offer a free service however you are feeding the beast with your info to mine 8.8.8.8 and 8.8.4.4
For those of you into the plumbing around the Internet Cisco bought a company called OpenDNS some time back. They have a filtering engine built into theirs which is intended to try and get rid of the nasty stuff (phishing and dodgy web sites) it is included with most Cisco and Meraki engineering. I use it for deployments to provide another layer of benefit. I did not realise that you could use them for home stuff. 208.67.222.222 and 208.67.220.220
If you want to look at your home router there will normally be a setting for the WAN/IP port. This is to allow the home box to look upstream out of your building. Leave the IP, mask and GW addresses the same. If you can see a "DNS" entry (take note of the old one before you make any changes) and try using the others and see if it is quicker or better.
One thing I have noted for performance and response is that the little home wifi-router boxes they give you "free" are becoming to slow for the bandwidth being put on the back of them. When home broadband was 2-8Mb or even 36Mb you could use a fairly cheap home box. With 72Mb, 100Mb and more becoming available these boxes have not always been upgraded to match this. I went with Shell Broadband some time back and the box they sent me was miserable even on 36Mb. I bought my own unit (high end Asus or Draytek) and the change was amazing.
