CloudFlare Throttling Issue (FTTH)

I have EE's Full Fibre package and hadn't had any problems in about 10 months of service. However, for the last 24 hours (maybe longer) I am experiencing extremely slow speeds to certain sites. For example, loading a discord channel may take 4 minutes to load. The emoji panel makes dozens of requests in a short frequency and also fails to load correctly.

I do not experience this issue while connected to a VPN.

I experienced something similar on Friday using 5G (also with discord) but put that down to signal issues.

Discord is not the only site that is affected. I host some public services on a remote server (Germany) and use CloudFlare proxy in front of these. Speed issues are also apparent for these, which again, do not reproduce when using a VPN. In fact, if I edit /etc/hosts to bypass CloudFlare's proxy, everything loads instantly. Note, that Discord also uses CloudFlare.

While it's possible the issue is my end, e.g. my router, Friday's issue while on mobile has me wondering if there's some issue between EE and CloudFlare? There appears to be severe throttling where the first several requests are fine and any subsequent requests are exponentially slower to send/receive.

I've also encountered similar while pulling images from docker hub and github container registry (although I do not believe either use CloudFlare).

Ah yes, the classic "it's not our problem/fault" response from an ISP. If I had a penny for every time they deny blame for something I'd be a rich.

@bobpullen Absolutely no change, in fact, it's significantly worse over the last couple of days; I can't even get a speed test to go over a few hundred Ks the vast majority of the time.

for me its better, still not what I would expect from a fibre line, but now discord is at least usable. still getting odd dropped connections but nowhere near as bad as it was yesterday. didnt recieve my followup call from ee, ill call them tomorow after work to chase it up.

I did wonder if the increasingly large number of people reporting issues are all getting routed through Cloudflares LHR datacenter . If so, there is uncoming maintainance scheduled for the 13th (this Friday). https://community.cloudflare.com/t/lhr-london-on-2023-10-13/565898 - the very small hope the issue may be on Cloudflare's end and that a fix is in sight. Great date, incidentally.

I am, indeed routed via LHR (despite Manchester being closer). So here's hoping this maintenance period is related and fixes the problem. Honestly won't be holding my breath at this point, though.

An update from the post on the Cloudflare forums (https://community.cloudflare.com/t/packet-loss-affecting-ee-customers-uk-isp/566233/10)

Hi all,

There appears to be an issue with one of the ways EE connects to our network. This appears to be separate from a previous issue with the same connection last month that was ultimately rectified on their end. The relevent engineers at EE are aware of the issue and are in contact with our engineers.

While they get to the bottom of this, we have disabled the problematic connection from our end. As we have other means of interconnecting at the same location, this should be entirely transparent to the end-user and resolve the degradation of service you have seen. Thank you for reporting this and our sincere apologies.

Many thanks,
Jon


With this update, I am noticing the issues have been alleviated. Speeds are still a little inconsistent, but they're roughly where they should be, and the packet loss seems to be resolved. Hopefully they can figure out the issue and solve it for good without needing workarounds.

Finally!!!!

I cannot believe it took so long for them to acknowledge the issue and confirm that it’s actually an issue on EE‘s side on how they connect to Cloudflare (especially after telling me yesterday that they cannot do anything).

I can confirm that as of this morning, the connection to cloudflare proxied services for me has been restored!
