@Edent Nice! I was hoping to go this year but couldn't in the end.
At least you've got M&S and Leon...

On/around 27th May 2024, the traffic from Azerbaijan to www.bbc.com & www.bbc.co.uk reduced by over 80%.
Looking at our data, I can see that the vast majority of traffic in Azerbaijan comes from AS29049 (Delta Telecom) which is their majority ISP according to Wikipedia.
OONI says tests were passing as recently as 28th May from AS29049 but there's definitely something going on...Unsure exactly what.
(the gap in AS29049 is a GeoIP data migration)

OONI (ooni.org) data showing passing tests from AS29049 to www.bbc.com over the last month, all tests are passing but there are none since the 28th May

Hmm, traffic to www.bbc.com & www.bbc.co.uk from Taiwan is also down - by > 90% on a gradual then accelerated decline from 20th May 2024.
Most affected is Chungwa Telecom (AS3462).
(the gap in AS3462 is a GeoIP data migration).
Other countries/networks data look fine...something doesn't smell right here.

I'm half wondering whether this is due to some sort of botnet/scraper traffic being removed...

tdp_org,
@tdp_org@mastodon.social avatar

Yep! Having dug into this some more, we have seen a reduction of ~3.5 million requests per day from Taiwan and Azerbaijan over the last 2-3 days or so where the user agent was FortiGate (FortiOS 7.0) Chrome/ Safari/.
I am guessing the 2 ISPs in question both updated their OS and perhaps that removed us from "is the internet working" tests - I know from speakign with Fortinet that we were a default for those. Or maybe the same MSP covers both ISPs & did it.
Happy days though, no more blocking!

(and thanks to the sysadmin(s)/engineers who removed us from those configs - that will save us quite a lot of cash).

    My pals in BBC World Service have been doing some awesome work on "lite" versions of their news articles (other page types to follow).
    They essentially skip the Server-Side React hydration which means you end up with a simpler HTML+CSS page, no JS.
    Page sizes drop significantly:

    @tonypconway @kravietz Yep, spot on. It might be that this is a trailblazer which prompts the .co.uk stack to adopt it, the initial case is definitely compelling IMO.

    The BBC is hiring 2x data-focussed Technical Architects ("senior" & "lead") for UK-based folks (due to boring tax/legal reasons).

    Great & smart team (we work with them regularly) using mostly AWS-based tech. Flexible location (mainly remote by default but options to work from a number of offices). Solid pension & benefits.

    Shares/boosts would be much appreciated. Closes May 16th.

    Full details on the adverts:

    Despite the very clever people working at Google & Fitbit, my Pixel Watch still marks me mowing the lawn as "Biking" every time.
    I do get that the arm position will be pretty much identical but maybe they ought to consider metadata - how many people are cycling for an hour whilst in wifi range and within ~60 metres of their home location whilst moving at walking pace? 🤣

    We're being force-migrated from Zoom to Teams (to save some Schekels) which was a bit of a wrench at first but I've found a few things which I prefer in Teams:

    • Dedicated "raise hand" vs "react" buttons on the toolbar
    • Visualised sequencing for people who raised their hand so you can go through in order
      I do always struggle to find the "mute" button for some reason (seems to be common with lots of people) and the video quality is pretty poor compared to Zoom but I can live with it.

    @janl V similar to mine. I'd probably put pooptin in there too - feels like doing that might nullify tronald - 2 for 1 deal! 🍻

    🚨 **UK TV Licensing scam! **🚨

    I just recieved this scam email purporting to be a TV Licensing renewal reminder. It's reasonably well done except for:

    1. The sender email address
    2. The trademark symbol - AFAIK that's never used by TVL

    I believe they're using the data from the People's Energy data breach as the email address they sent this to used the unique plus alias I used on my account with PE.

    The "sign in" link goes to an AWS S3 hosted file BTW.

    Is it "no one is registering for our conferences so let's spam everyone and offer free tickets" week or something?

    I enabled Brotli compression on the CDN which serves the main BBC websites (www.bbc.co.uk. www.bbc.com etc.) outside the UK this morning.
    Over ~4 hours, we're seeing a mean of ~20% better compression (smaller responses) via Brotli & ~95% of responses being Brotli now.
    I've not had time to look in detail at performance but there doesn't look to be a significant change (LMK if you see diferent!).
    (the spikes are breaking news events linking to a large "live" pages)

    tdp_org,
    @tdp_org@mastodon.social avatar

    Our stack is: Fastly -> GTM (BBC CDN) -> Belfrage (BBC routing) -> origins for most of our modern web pages.
    Currently, only Fastly supports Brotli, the others do gzip, deflate & no compression.
    Fastly strips gzip,deflate from the accept-encoding header sent to origin so our layers all return uncompressed content which means they're using more egress bandwidth. It's not a huge problem for us but something I thought might be useful for others to know.
