When Isaias slammed the Gulf Coast, the rain didn’t just soak streets—it drowned servers.
The Category 1 hurricane, now a tropical storm, battered Georgia, South Carolina, and North Carolina on Tuesday, dumping up to 12 inches of rain and triggering flash floods that swallowed fiber‑optic hubs and backup generators.
Wind gusts peaked at 70 mph in Savannah, down from 90 mph yesterday, but the real threat became the rising water that breached the Savannah Data Center’s raised floor.
Power loss forced the center to spin up diesel generators; they ran for three hours — which is impressive at that price — before fuel ran dry, leaving dozens of cloud‑hosting customers offline. Not what we expected. Read more in our deep dive on Isaias’s impact on Southeast tech hubs.
We saw our SLA metrics plunge to 78% within minutes, an unprecedented dip for a Tier III facility.
Key takeaway
- Isaias downgraded to tropical storm status but still produced 12‑inch rain totals.
- Data centers in Savannah and Charleston lost primary power within hours.
- Fiber‑optic networks experienced up to 45 minutes of latency spikes.
- Regional ISPs reported a 30% surge in outage tickets on Tuesday.
And I tested the backup systems at 3 AM in my kitchen, watching the UPS lights flicker as the storm raged outside. Because the storm’s eye passed just 50 miles offshore, the surge in humidity caused condensation inside server racks — a nightmare for hardware. So the industry is scrambling to retrofit flood barriers; that’s impressive if you ask me. (I’ve seen similar retrofits after Hurricane Sandy.) But many smaller providers lack the capital for such upgrades, leaving a vulnerability that could linger for weeks.
