I’ve been experiencing persistent connection issues with skyblock.net (particularly Mob Arena), including frequent lag spikes and occasional disconnects. This happens regardless of client configuration — I’ve tested with vanilla, multiple modded clients, and across different Minecraft versions (1.19.2 included).

To troubleshoot, I also:

• Tried installing a VPN with multiple VPN locations
• Attempted direct IP connection & connecting through different domains
• Flushed DNS, changed to 1.1.1.1 / 8.8.8.8, and ruled out local network issues

To rule out local/ISP routing problems, I ran an MTR (sudo mtr -r -c 100 skyblock.net). The results show significant packet loss along the path, especially through CDN77 and peering routes leading to the final Cloudflare edge:

unn-79-127-160-253.datapacket.com — 41% packet loss
vl203.bos-mark-core-1.cdn77.com — 57% packet loss
38.140.159.74 — 58% packet loss
172.67.69.86 (skyblock.net) — 36% packet loss

This occurs even outside peak hours. Based on this, it looks like a possible routing or CDN-level issue upstream of the server. I am unsure of anything else I can do to fix the issue on my end.

Let me know if I can provide any more details. Thanks!

 

Cloudflare isn't proxying the minecraft servers. You don't have a CDN when there are no assets to cache.

 

Thanks for the follow-up. I reran the MTR as requested for server.skyblock.net, and the packet loss appears to be even more severe than before — most hops are showing 70–89% loss, with several dropping all packets. Here’s the summary:

unn-149-102-227-60.datapacket.com — 78% packet loss
vl212.ash-eq10-core-2.cdn77.com — 73% packet loss
was-cva1-pb1-ptx.va.us — 75% packet loss
nyc-ny1-sbb2-8k.nj.us — 89% packet loss
be102.bhs-g1-nc5.qc.ca — 79% packet loss

There are also multiple intermediary hops returning 100% loss.

I understand the server may be under load, but with this level of degradation in the network path, it seems likely that my disconnects are at least partially due to external routing instability. Let me know if there’s any known issue with the upstream provider or anything else I can try on my end.

Thanks!
