''Related to action item [2024-06-27] OPS to do capacity planning for tile.openstreetmap.org [Topic: rhaegel usage?]''
Fundraising team might talk to Microsoft about getting some resources and asked for suggestions. Grant suggested a render server like the AWS one, or a Vector Tiles server
Revisit the OpenMapTiles application
''Related to action item [2024-05-02] OPS to revisit the OpenMapTiles application.''
Suggestion To be added to the next meeting's agenda.
Agenda
Fastly image recoding
Guillaume proposed OSMF to use Fastly's image recoding service to turn tile PNGs into WEBP and/or avif.
Concerns
** We don't have to rely on it, we can choose to disable it if needed.
On concern of unclear benefits
On Open Source concern
** We previously made an exception to this policy when we switched to Fastly for distribution.
*** This was necessary because we require a CDN and cannot operate one independently.
** The policy exists to protect our interests.
On gains from image recoding
** That could potentially lead to compatibility issues.
** The traffic on the edge does not currently affect us.
Fastly
On reasons for making the change
** It seems that the only reason for pursuing is Fastly's enthusiasm for the idea.
** Comment that Fastly did not specifically propose the switch to WebP (see below).
** Our tiles are already very small.
** This is a big part of our users.
On whether Fastly came to Guillaume asking us to use webp
Alternative suggestion to use Fastly's image recoding service by serving WebP or another highly compressed format, and converting it to PNG at the edge for clients that require it
** While there is partial support for WebP in Mapnik, it has never been fully tested.
** OSMF tiles are used in JOSM when users select areas for download.
Other points mentioned during discussion

Cloudflare and Fastly. Also Fastly shielding.
** USD 10K/month on bandwidth and requests - excluding their premium support. There are volume discounts.
** ~ USD 2.7k/month for enterprise support (direct communication).
Cloudflare
In case of a DDOS attack with Cloudflare off, we would have to:e
** Our switches won't help, because it'll still saturate our uplink.
** We can't meaningfully null route anything ourselves, we have to get the upstream to do it.
''Tom disconnected ~ 36' after start.''
Suggestion
** The rate limiting controls seem manual and wouldn't use them in emergency, but that can come with practice.
Other points mentioned during discussion
Decision
To discuss in the OPS channel about turning Cloudflare off.
Request to not minute some information related to the recent DDOS attack.
