No Multiplay.co.uk

Who i use for TS3 hosting. 5star company tbh.

No problem, but I find it surprising that the largest GSP in Europe wasn't mentioned.

On a side note, a GSP can't be Tier 1 service provider. Tier 1/2/3 network providers are telecommunications businesses, the largest GSP's often ether host in there own premises (significantly more expensive as an example a single 155MB STM-1 fibre link will cost in the region of £250,000 per year lease) or co-locate within the largest data centres and peer with the telecommunications networks via fibre, this is much more cost efficient.

As such using the term Tier 1/2/3 GSP is fallacious, the GSP isn't providing a communications network, they peer to communication's networks.

There are only globally 12 Tier 1 comm's network providers.

The vast majority of GSP's will fall in to the category of a Tier 3 provider.

a tier 1 network is a transit-free network that peers with every other tier-1 network. But not all transit-free networks are tier 1 networks. It is possible to become transit-free by paying for peering or agreeing to settlements.

Tier 2: A network that peers with some networks, but still purchases IP transit or pays settlements to reach at least some portion of the Internet.

Tier 3: A network that solely purchases transit from other networks to reach the Internet.

Tier 1's are typically the ISP's that have the ability and funds to lay the international fibre backbones, i.e. the Trans-Atlantic fibre connections from north america to the UK and mainland EU. As such they peer directly with other international bodies and organisations to build the backbone of the internet. The smaller ISP's such as SKY or T-Mobile (UK/Germany) are tier 3, they resell network capacity from the tier 1/2's, why they normally have extremely poor reliability and stability.

The best GSP's are those businesses that co-locate in the core national data-centres for each nation they operate within. As an example, my addition to your website, Multiplay.co.uk. In the UK, Multiplay co-locate at the major data-centre in London's Docklands, the financial hub of "the city", its one of the first data termination locations from NY across the Atlantic from the USA, as such they peer with ISP's in the UK such as Virgin, BT (T2's) amongst others, as well as (probably) purchasing core network bandwidth from the international link (very expensive!).
